HEMSWORTH (off-screen): There's
nothing quite like the ocean
5
00:00:19,360 --> 00:00:20,320
at first light.
6
00:00:25,040 --> 00:00:26,360
It's a special place.
7
00:00:30,480 --> 00:00:33,440
But you're always aware
there may be bigger creatures
8
00:00:33,520 --> 00:00:34,800
out there than you.
9
00:00:35,520 --> 00:00:38,280
HEMSWORTH: I've spent a
big part of my life in
and around the ocean,
10
00:00:38,360 --> 00:00:40,720
but I've never seen a
shark when I've been surfing.
11
00:00:41,120 --> 00:00:43,040
I've been called out of the
water by the helicopters,
12
00:00:43,120 --> 00:00:46,440
the shark spotters
a couple of times.
13
00:00:47,600 --> 00:00:49,800
Been in the water
when other people have said
14
00:00:49,880 --> 00:00:50,840
they've seen the shark.
15
00:00:50,920 --> 00:00:53,880
But you definitely
feel their presence.
16
00:00:53,960 --> 00:00:56,520
I've had a couple of
spooky moments where I'm
17
00:00:56,600 --> 00:00:58,120
pretty certain that
there was something
18
00:00:58,200 --> 00:00:59,920
swimming underneath me.
19
00:01:11,280 --> 00:01:14,360
HEMSWORTH (off-screen): For me,
sharks are some of the planet's
most elegant and
20
00:01:14,440 --> 00:01:15,960
magnificent creatures.
21
00:01:24,480 --> 00:01:27,160
Unfortunately when we
humans enter the water,
22
00:01:27,320 --> 00:01:29,720
they can present
unique dangers.
23
00:01:32,440 --> 00:01:34,120
In Australia, where I live,
24
00:01:34,200 --> 00:01:36,000
we've just had the worst
spate of fatal shark
25
00:01:36,080 --> 00:01:38,120
encounters in a century.
26
00:01:38,200 --> 00:01:39,920
REPORTER (over TV):
The community is on
edge this morning,
27
00:01:40,000 --> 00:01:41,440
after a man was killed
by a great white shark...
28
00:01:41,520 --> 00:01:44,200
REPORTER 2 (over TV):
A boy, just 15, dead
after a shark attack...
29
00:01:46,840 --> 00:01:48,760
HEMSWORTH (off-screen): As
someone who loves sharks,
30
00:01:49,160 --> 00:01:51,120
and being in the water,
31
00:01:51,200 --> 00:01:53,360
I want to get beneath
that reputation.
32
00:01:57,720 --> 00:02:00,200
See what makes these
creatures tick,
33
00:02:00,960 --> 00:02:03,480
and maybe even
meet one in person.
34
00:02:05,480 --> 00:02:08,000
I want to find out if
we can live together,
35
00:02:08,800 --> 00:02:10,920
without doing each other harm.
36
00:02:18,200 --> 00:02:21,360
DIRECTOR (off-screen):
So if someone says the
word sharks to you Chris...
37
00:02:21,440 --> 00:02:22,240
HEMSWORTH: Yeah.
38
00:02:22,320 --> 00:02:23,920
DIRECTOR (off-screen):
What comes to mind?
39
00:02:24,640 --> 00:02:27,520
HEMSWORTH: I have a very
mixed kind of gut reaction
40
00:02:27,600 --> 00:02:29,800
to sharks these days, you know.
41
00:02:30,200 --> 00:02:33,960
Obviously I grew up
watching Jaws and plenty
of films like that,
42
00:02:34,040 --> 00:02:37,360
that scare the hell out
of you, and you know,
43
00:02:37,520 --> 00:02:39,520
make you think twice
about getting in the ocean.
44
00:02:39,600 --> 00:02:42,240
But we need to figure
out a way to work and
45
00:02:42,840 --> 00:02:46,160
live in harmony
with them, so you know,
46
00:02:46,400 --> 00:02:48,640
we're protected
but also so are they.
47
00:02:58,480 --> 00:03:00,880
HEMSWORTH (off-screen):
Growing up in paradise,
48
00:03:00,960 --> 00:03:03,360
you learn about the beauty
and importance of the natural
49
00:03:03,440 --> 00:03:05,240
world pretty early on.
50
00:03:13,560 --> 00:03:16,840
That's me, with my mum,
dad and big brother.
51
00:03:17,960 --> 00:03:20,280
I was always encouraged
to appreciate the
52
00:03:20,360 --> 00:03:22,120
wilderness around me.
53
00:03:24,800 --> 00:03:26,480
It means generally
I don't think twice about
54
00:03:26,600 --> 00:03:28,640
getting in the water.
55
00:03:28,960 --> 00:03:31,680
No matter what might
be lurking out there.
56
00:03:31,760 --> 00:03:33,080
Where, are you
thinking, here or...
57
00:03:33,160 --> 00:03:36,400
MICK: I'm thinking here,
down this way.
58
00:03:37,640 --> 00:03:40,480
HEMSWORTH (off-screen): My
mate Mick Fanning shares a
similar love of the ocean,
59
00:03:40,760 --> 00:03:43,880
despite some troubling
first-hand experience.
60
00:03:45,800 --> 00:03:47,280
MICK: I don't know.
HEMSWORTH: Yeah.
61
00:03:47,360 --> 00:03:48,600
MICK: We'll figure it
out once we get out there.
62
00:03:48,680 --> 00:03:50,560
HEMSWORTH: Any sharks?
MICK: Probably.
63
00:03:50,640 --> 00:03:54,560
Yeah, we're in an area
that is known for sharks.
64
00:03:54,640 --> 00:03:56,000
HEMSWORTH: Yeah.
65
00:03:56,080 --> 00:03:58,160
MICK: Been a bit more
activity around lately.
66
00:03:58,240 --> 00:03:59,480
HEMSWORTH:
There has, hasn't there?
67
00:03:59,560 --> 00:04:01,320
MICK: Maybe we'll go and
do it before they show up.
68
00:04:01,400 --> 00:04:03,160
HEMSWORTH: That's right.
Shall we get out there?
69
00:04:03,240 --> 00:04:05,000
MICK: Yeah, let's go do it.
70
00:04:06,200 --> 00:04:08,680
HEMSWORTH (off-screen): Now
I'm competitive by nature,
71
00:04:08,760 --> 00:04:11,120
so I love to think I
can keep up with Mick.
72
00:04:12,280 --> 00:04:14,000
Just one problem.
73
00:04:14,080 --> 00:04:16,320
He's a three time
world champion.
74
00:04:17,040 --> 00:04:18,640
MICK: Is it like a real heat?
75
00:04:18,720 --> 00:04:20,080
HEMSWORTH:
This is the world title.
76
00:04:20,160 --> 00:04:21,320
MICK: Awesome.
77
00:04:21,400 --> 00:04:23,840
HEMSWORTH (off-screen): Maybe
intimidation is my best bet.
78
00:04:24,080 --> 00:04:27,960
HEMSWORTH: We're friends now,
but once we hit the water,
we're enemies.
79
00:04:28,040 --> 00:04:29,600
MICK: You're not
riding that, are you?
80
00:04:29,680 --> 00:04:31,480
HEMSWORTH: I am.
Are you riding that?
81
00:04:31,560 --> 00:04:33,160
(laughter).
82
00:04:33,240 --> 00:04:35,320
HEMSWORTH: I hope
you fall off.
83
00:04:35,400 --> 00:04:37,120
(laughter).
84
00:04:37,200 --> 00:04:39,280
HEMSWORTH (off-screen):
Nope, that didn't work.
85
00:04:39,760 --> 00:04:42,760
Maybe it's time to take
up a different sport.
86
00:04:51,160 --> 00:04:53,640
Bowling, cricket, tennis...
87
00:05:03,720 --> 00:05:06,400
I think it's fair to say
I'm obsessed with surfing.
88
00:05:06,800 --> 00:05:09,400
I have been since the first
time I tried it with my dad
89
00:05:09,560 --> 00:05:12,560
and my brothers when
I was six years old.
90
00:05:15,200 --> 00:05:18,240
You get so wrapped up in the
waves, it's easy to forget,
91
00:05:18,320 --> 00:05:20,600
we're really just visitors.
92
00:05:23,360 --> 00:05:26,600
Below us, a whole
other world...
93
00:05:30,600 --> 00:05:32,240
Where sharks have been
feeding for hundreds of
94
00:05:32,320 --> 00:05:34,640
millions of years.
95
00:05:36,200 --> 00:05:38,920
And it's here our
paths sometimes cross.
96
00:05:42,360 --> 00:05:44,600
HEMSWORTH: You've
probably talked about
this about 500 times
97
00:05:44,680 --> 00:05:45,840
since it happened...
98
00:05:45,920 --> 00:05:47,200
MICK: A few.
99
00:05:48,640 --> 00:05:49,760
HEMSWORTH: A few times.
100
00:05:49,840 --> 00:05:51,480
Do you want to
walk us through it?
101
00:05:51,560 --> 00:05:53,400
MICK: It was a beautiful day.
102
00:05:53,960 --> 00:05:57,000
It was extremely sunny,
water was picture perfect clear.
103
00:05:57,800 --> 00:06:00,800
And you know, we're in the
middle of a surfing event.
104
00:06:03,680 --> 00:06:05,960
You know, we had just started
the final with Julian Wilson.
105
00:06:07,160 --> 00:06:08,960
MAN (over TV): Beautiful carve
to start from Wilson.
106
00:06:09,520 --> 00:06:11,720
MICK: And I'd been sitting
there for probably like four
107
00:06:11,800 --> 00:06:13,160
or five minutes.
108
00:06:16,320 --> 00:06:20,360
And I was just about to move
and then I just heard this
109
00:06:20,440 --> 00:06:23,920
splash behind me, and
I was like, oh no.
110
00:06:26,520 --> 00:06:31,000
And I try and jump on my
board and then all of a sudden,
111
00:06:31,080 --> 00:06:33,040
I just get hit from this side.
112
00:06:34,600 --> 00:06:36,880
I just caught the tail
straight to the face.
113
00:06:38,880 --> 00:06:40,600
And I'm just like,
I'm out of here.
114
00:06:40,680 --> 00:06:41,920
It was...
115
00:06:44,240 --> 00:06:47,080
But then I was like, hang
on, if I just keep swimming,
116
00:06:47,160 --> 00:06:49,440
this thing could just
come and take my legs,
117
00:06:49,520 --> 00:06:51,680
so I was just trying to
get myself up as high as I
118
00:06:51,760 --> 00:06:53,880
possibly could to see
if it was coming up.
119
00:06:53,960 --> 00:06:54,920
HEMSWORTH: Oh wow.
120
00:06:55,000 --> 00:06:57,000
MICK: And luckily it didn't.
121
00:06:57,080 --> 00:06:58,400
HEMSWORTH:
What kind of shark was it?
122
00:06:58,480 --> 00:06:59,680
MICK: It was a great white.
HEMSWORTH: A great white?
123
00:06:59,760 --> 00:07:01,720
MICK: Yeah.
124
00:07:03,200 --> 00:07:05,000
HEMSWORTH: How long before
the jet ski picked you up?
125
00:07:05,120 --> 00:07:08,040
MICK: Oh it would have been
probably like maybe 30 seconds.
126
00:07:08,120 --> 00:07:09,840
HEMSWORTH: Oh, that's the
longest 30 seconds of your life.
127
00:07:09,920 --> 00:07:11,240
MICK: Yeah.
128
00:07:11,320 --> 00:07:12,400
HEMSWORTH:
After that happened,
129
00:07:12,480 --> 00:07:15,200
did you find you have
more trepidation,
130
00:07:15,280 --> 00:07:17,200
hesitation getting
in the water.
131
00:07:17,400 --> 00:07:20,600
MICK: Definitely things
have changed now.
132
00:07:20,680 --> 00:07:23,760
Like, I see everything
on the water now.
133
00:07:26,680 --> 00:07:29,720
And I'm still scared of
hearing splashes behind me.
134
00:07:29,800 --> 00:07:32,000
It just, I jump.
135
00:07:33,400 --> 00:07:37,080
And even if the waves
are incredibly perfect,
136
00:07:37,440 --> 00:07:40,000
if I just don't feel right,
I just go in these days.
137
00:07:40,080 --> 00:07:41,040
HEMSWORTH: Yeah, yeah.
138
00:07:41,120 --> 00:07:44,440
MICK: It's just,
you know, just...
139
00:07:44,520 --> 00:07:46,480
It's not worth the risk.
140
00:07:52,080 --> 00:07:54,800
HEMSWORTH (off-screen):
Mick was extremely lucky,
141
00:07:54,880 --> 00:07:57,600
because encounters like
these can turn deadly.
142
00:08:13,160 --> 00:08:16,400
Sharks can bite with
such power and speed,
143
00:08:17,480 --> 00:08:19,680
even if they don't
intend to kill,
144
00:08:19,760 --> 00:08:22,360
the outcome can
be catastrophic.
145
00:08:31,400 --> 00:08:33,160
REPORTER (over TV):
Good evening, a surfer
has been mauled and his
146
00:08:33,240 --> 00:08:36,120
board obliterated by a
five meter great white shark,
147
00:08:36,800 --> 00:08:39,120
a predator that
came out of nowhere.
148
00:08:41,920 --> 00:08:45,800
HEMSWORTH (off-screen):
In 2020 Australia suffered
a record eight fatal
149
00:08:45,880 --> 00:08:49,320
shark encounters, over
half along the east coast,
150
00:08:49,400 --> 00:08:50,880
where I live.
151
00:08:51,640 --> 00:08:53,600
REPORTER (over TV):
The hunt is on for the
great white shark that
152
00:08:53,680 --> 00:08:56,160
killed a 46 year old surfer
at Greenmount Beach at
153
00:08:56,240 --> 00:08:57,960
Coolangatta on the Gold Coast.
154
00:08:59,200 --> 00:09:01,320
HEMSWORTH (off-screen): Every
loss of life, devastating.
155
00:09:02,440 --> 00:09:04,920
REPORTER (over TV):
A loving father,
husband and keen fisherman,
156
00:09:05,000 --> 00:09:07,080
mauled by a shark
off Fraser Island.
157
00:09:08,160 --> 00:09:10,480
HEMSWORTH (off-screen):
With huge repercussions
in these coastal communities.
158
00:09:11,560 --> 00:09:13,240
REPORTER (over radio): It's
the second fatal shark attack
159
00:09:13,320 --> 00:09:16,000
in the state's north in
just over a month.
160
00:09:18,920 --> 00:09:20,600
HEMSWORTH (off-screen):
Despite these tragedies,
161
00:09:20,680 --> 00:09:22,920
it remains highly unlikely
that any of us in Australia
162
00:09:23,000 --> 00:09:24,920
will be bitten by a shark.
163
00:09:28,160 --> 00:09:30,320
But it does seem that
human encounters with
164
00:09:30,400 --> 00:09:32,520
them are increasing.
165
00:09:35,520 --> 00:09:38,000
So what exactly is happening
out there in our oceans that
166
00:09:38,080 --> 00:09:39,680
can explain this?
167
00:09:45,520 --> 00:09:48,200
PAUL: So if we're starting here
on the top end of Queensland,
168
00:09:48,440 --> 00:09:50,120
come down the
east coast of Australia...
169
00:09:50,200 --> 00:09:53,560
HEMSWORTH (off-screen): Paul
Butcher is one of Australia's
top shark scientists.
170
00:09:53,640 --> 00:09:56,000
He's spent the last 20 years
researching their changing
171
00:09:56,120 --> 00:09:57,800
behavior and movements.
172
00:09:59,360 --> 00:10:01,960
PAUL: For white sharks,
the migration route is as
173
00:10:02,000 --> 00:10:04,400
a group during April,
May, up the east coast,
174
00:10:04,840 --> 00:10:07,240
and we've got a location
here called Fraser Island.
175
00:10:07,520 --> 00:10:09,440
Once you get to October,
November, December,
176
00:10:09,520 --> 00:10:11,960
they're turning around and
coming back down to Victorian
177
00:10:12,000 --> 00:10:13,640
and Tasmanian waters.
178
00:10:14,280 --> 00:10:16,880
The big thing is we've got
this very heavy populated
179
00:10:16,960 --> 00:10:19,360
coast line through here, so
we've got large numbers of
180
00:10:19,440 --> 00:10:21,200
people now using the
east coast of Australia,
181
00:10:21,280 --> 00:10:24,200
warm water, beautiful
conditions, great waves.
182
00:10:24,280 --> 00:10:26,320
HEMSWORTH: So it's
just that there's more
people in the water.
183
00:10:26,400 --> 00:10:28,200
PAUL: More people, but we're
definitely seeing more sharks
184
00:10:28,280 --> 00:10:29,480
up against the coastline.
185
00:10:29,560 --> 00:10:30,760
HEMSWORTH: So why do
you think they're coming
186
00:10:30,840 --> 00:10:31,720
closer to shore?
187
00:10:31,800 --> 00:10:33,200
Is that the water
temperatures?
188
00:10:33,280 --> 00:10:35,200
PAUL: So we've got this warm
current that comes down along
189
00:10:35,280 --> 00:10:36,840
the east Australian coast.
190
00:10:36,920 --> 00:10:39,000
That nearly runs the entire
year now, where previously,
191
00:10:39,080 --> 00:10:41,000
over decades and decades,
192
00:10:41,080 --> 00:10:43,080
it just runs during
summer and spring.
193
00:10:43,160 --> 00:10:44,280
HEMSWORTH: And it
runs the entire year,
194
00:10:44,360 --> 00:10:45,640
you think because of...
195
00:10:45,720 --> 00:10:46,880
PAUL: Global warming.
196
00:10:46,960 --> 00:10:48,920
So we've now got those
warm temperatures,
197
00:10:49,000 --> 00:10:51,200
we're starting to see more
animals along the coastline,
198
00:10:51,280 --> 00:10:53,160
which is an increase
in sharks as well.
199
00:10:53,240 --> 00:10:55,920
So it's inevitable that we're
going to see white sharks and
200
00:10:56,000 --> 00:10:59,120
other sharks interacting with
human users in the water.
201
00:11:02,400 --> 00:11:04,680
HEMSWORTH (off-screen):
It now seems like our
altering of the climate
202
00:11:04,760 --> 00:11:07,880
might be drawing an
increasing number of sharks
203
00:11:07,960 --> 00:11:10,200
closer to shore.
204
00:11:13,240 --> 00:11:16,920
Our world, it seems, is
having a big impact on theirs.
205
00:11:22,080 --> 00:11:23,760
The best way to
really get a handle on
206
00:11:23,840 --> 00:11:25,120
what's going on down there...
207
00:11:25,280 --> 00:11:26,840
HEMSWORTH (over radio): Oh wow.
208
00:11:27,000 --> 00:11:30,240
HEMSWORTH (off-screen):
Is to take a dip and
see it for yourself.
209
00:11:37,440 --> 00:11:39,600
HEMSWORTH: So we're about to
go and see the legendary shark
210
00:11:39,680 --> 00:11:41,240
conservationist
Valerie Taylor,
211
00:11:41,320 --> 00:11:42,920
and we're going to go diving,
212
00:11:43,440 --> 00:11:44,640
hopefully see some sharks,
213
00:11:45,120 --> 00:11:47,640
hopefully some
friendly sharks.
214
00:11:50,000 --> 00:11:52,480
HEMSWORTH (off-screen): Valerie
Taylor started her career as a
champion spear fisher.
215
00:11:58,520 --> 00:12:00,480
But she soon fell in
love with the ocean,
216
00:12:00,560 --> 00:12:02,720
and dedicated her
life to conservation.
217
00:12:05,360 --> 00:12:07,560
She swapped her
spear for a camera,
218
00:12:07,640 --> 00:12:09,400
and started making
marine documentaries with
219
00:12:09,480 --> 00:12:11,440
her husband Ron.
220
00:12:11,520 --> 00:12:13,320
VALERIE (off-screen): Great
whites are most dangerous,
221
00:12:13,400 --> 00:12:15,480
when they feel
themselves to be trapped.
222
00:12:17,920 --> 00:12:21,560
HEMSWORTH (off-screen): They
specialized in filming sharks
in their natural habitat.
223
00:12:21,640 --> 00:12:26,000
VALERIE (off-screen): It was
an extremely risky method of
filming these big predators.
224
00:12:26,080 --> 00:12:28,320
HEMSWORTH (off-screen):
And even helped shoot the
Hollywood blockbuster
225
00:12:28,400 --> 00:12:30,000
Jaws.
226
00:12:31,520 --> 00:12:34,680
I grew up watching
Valerie's shows, and at 85,
227
00:12:34,760 --> 00:12:38,000
she still cares deeply about
the health of our oceans.
228
00:12:40,040 --> 00:12:40,920
Hey Valerie.
229
00:12:41,000 --> 00:12:41,880
VALERIE: G'day Chris.
230
00:12:42,440 --> 00:12:43,560
HEMSWORTH: Good to see you.
How's it going?
231
00:12:43,640 --> 00:12:45,320
VALERIE: Fine.
HEMSWORTH: Great.
232
00:12:45,400 --> 00:12:46,640
So what's the plan today?
233
00:12:46,720 --> 00:12:51,080
VALERIE: We're going out to
Fish Rock, and if we're lucky,
234
00:12:52,800 --> 00:12:54,360
we'll see grey nurse sharks.
235
00:12:54,440 --> 00:12:55,280
HEMSWORTH: Fantastic.
236
00:12:55,360 --> 00:12:57,000
So what's the temperament
of a grey nurse shark?
237
00:12:57,080 --> 00:12:58,480
VALERIE: It's a very
easygoing shark.
238
00:12:59,000 --> 00:13:00,360
HEMSWORTH: Easygoing, yeah.
239
00:13:00,480 --> 00:13:02,040
VALERIE: Yeah.
They will come close.
240
00:13:02,120 --> 00:13:02,960
HEMSWORTH: Great.
241
00:13:03,040 --> 00:13:05,120
VALERIE: Don't make
sharp movements, you know,
242
00:13:05,200 --> 00:13:06,360
like this.
243
00:13:06,440 --> 00:13:07,280
Don't do that.
244
00:13:07,360 --> 00:13:09,320
They'll thump your
tail, you'll hear it.
245
00:13:09,400 --> 00:13:10,320
HEMSWORTH: Yeah, right.
246
00:13:10,400 --> 00:13:12,840
VALERIE: And they go away,
it means they're cross.
247
00:13:12,920 --> 00:13:13,720
HEMSWORTH: Okay.
248
00:13:13,840 --> 00:13:14,880
VALERIE: But you're
not going to do that.
249
00:13:14,960 --> 00:13:16,160
HEMSWORTH:
We're not going to do that.
250
00:13:16,240 --> 00:13:17,040
Okay. Great.
251
00:13:17,120 --> 00:13:18,680
VALERIE: Well let's go.
HEMSWORTH: Let's go.
252
00:13:20,520 --> 00:13:22,760
HEMSWORTH (off-screen):
Fish Rock, off the coast
of New South Wales,
253
00:13:22,840 --> 00:13:25,520
is a very special
place for Val,
254
00:13:25,600 --> 00:13:27,960
and the story of
shark conservation.
255
00:13:31,600 --> 00:13:34,040
And today is going to
be her first visit back in
256
00:13:34,120 --> 00:13:35,720
over a decade.
257
00:13:36,080 --> 00:13:37,760
VALERIE: You look like
you're in the tropics.
258
00:13:37,840 --> 00:13:39,800
I look like I'm in Antarctica.
259
00:13:39,880 --> 00:13:41,440
(laughter).
260
00:13:43,160 --> 00:13:47,320
HEMSWORTH (off-screen): 50 years
ago it was thought that grey
nurse sharks were killers,
261
00:13:47,400 --> 00:13:48,560
so they were culled,
262
00:13:48,640 --> 00:13:50,480
and almost became
extinct in Australia.
263
00:13:54,240 --> 00:13:59,280
But Val started campaigning,
and thanks to her efforts,
264
00:13:59,520 --> 00:14:02,560
the grey nurse was the first
species of shark in the world
265
00:14:02,640 --> 00:14:04,400
to gain protection.
266
00:14:11,720 --> 00:14:13,880
I don't think there's anyone
out there who knows these
267
00:14:13,960 --> 00:14:15,480
creatures better than Val.
268
00:14:15,640 --> 00:14:18,560
VALERIE: Sharks are the
garbage men of the sea.
269
00:14:19,000 --> 00:14:21,560
They eat the old, the
sick and the unwary.
270
00:14:22,160 --> 00:14:23,640
They don't eat people.
271
00:14:23,840 --> 00:14:25,120
They bite them.
272
00:14:25,200 --> 00:14:26,320
HEMSWORTH: And spit them out.
273
00:14:26,400 --> 00:14:27,320
VALERIE: Spit them out.
274
00:14:27,400 --> 00:14:28,760
Wrong thing, made a mistake.
275
00:14:28,840 --> 00:14:31,600
They don't have hands,
they can't go and say, ooh...
276
00:14:31,680 --> 00:14:33,080
Oh nice.
277
00:14:33,160 --> 00:14:34,200
(laughter).
278
00:14:34,920 --> 00:14:40,760
VALERIE: They bite and they
have to feel with their teeth.
279
00:14:40,880 --> 00:14:43,840
You know, if I bit
you, no, not me, if a shark
280
00:14:43,920 --> 00:14:45,680
HEMSWORTH: You can
bite me, it's alright.
281
00:14:45,880 --> 00:14:47,400
VALERIE:
Bit you with its teeth,
282
00:14:48,440 --> 00:14:51,240
your first instinct
would be to pull away,
283
00:14:51,640 --> 00:14:53,800
but if you stay still,
they'll let go.
284
00:14:53,880 --> 00:14:55,440
But nobody can stay still.
285
00:15:02,680 --> 00:15:05,080
HEMSWORTH (off-screen): Now I'm
a total diving novice...
286
00:15:05,160 --> 00:15:06,440
HEMSWORTH: Should I be nervous?
287
00:15:06,520 --> 00:15:08,240
(laughter).
288
00:15:08,320 --> 00:15:10,520
HEMSWORTH (off-screen): But
I reckon I'm in safe hands.
289
00:15:15,720 --> 00:15:19,600
Val's completed over 5,000
dives in the last 60 years,
290
00:15:21,200 --> 00:15:23,440
and knows this place like
the back of her hand.
291
00:15:24,760 --> 00:15:26,160
VALERIE (over radio):
It's a bit murky down here.
292
00:15:27,640 --> 00:15:30,240
Chris, are you okay?
293
00:15:30,560 --> 00:15:32,320
HEMSWORTH (over radio):
Yep, all good.
294
00:15:34,840 --> 00:15:37,680
HEMSWORTH (off-screen):
Although 40 feet underwater,
looking for giant sharks,
295
00:15:38,360 --> 00:15:40,800
I do wish I could
see a bit further.
296
00:15:52,560 --> 00:15:55,280
Val says the grey nurses
we're hoping to see can grow
297
00:15:55,480 --> 00:15:58,160
up to 12 feet long,
298
00:16:00,720 --> 00:16:03,640
and live for up to 40 years.
299
00:16:09,200 --> 00:16:10,480
VALERIE (over radio):
Oh, look, look.
300
00:16:10,560 --> 00:16:12,120
HEMSWORTH (over radio): Oh wow.
301
00:16:16,600 --> 00:16:19,240
VALERIE (over radio):
That's a big female.
302
00:16:20,920 --> 00:16:22,400
HEMSWORTH (over radio):
Incredible.
303
00:16:33,600 --> 00:16:36,400
HEMSWORTH (off-screen):
Coming face to face with them,
304
00:16:38,480 --> 00:16:42,040
it's hard to put into
words the serene beauty
305
00:16:42,120 --> 00:16:44,440
of these magnificent
creatures.
306
00:16:56,480 --> 00:16:59,680
Up close you see the grey
nurse's jaws are filled with
307
00:16:59,760 --> 00:17:02,800
over 100 needle-sharp teeth.
308
00:17:02,880 --> 00:17:04,800
HEMSWORTH (over radio):
Just amazing.
309
00:17:06,200 --> 00:17:08,640
HEMSWORTH (off-screen):
But luckily, they only
eat small fish and
310
00:17:08,720 --> 00:17:11,400
crustaceans from the sea floor.
311
00:17:16,880 --> 00:17:18,960
It's such a privilege
seeing these massive
312
00:17:19,040 --> 00:17:20,920
creatures up close.
313
00:17:23,520 --> 00:17:25,040
Being under the waves,
314
00:17:25,120 --> 00:17:29,320
rather than surfing
on top really does give
you a new perspective.
315
00:17:35,400 --> 00:17:36,400
VALERIE: How was it?
316
00:17:36,480 --> 00:17:37,520
HEMSWORTH: It's amazing.
317
00:17:37,600 --> 00:17:39,480
Well, it was amazing for me.
318
00:17:39,560 --> 00:17:45,320
I saw one and then it kind
of swam off pretty quick,
319
00:17:45,960 --> 00:17:48,560
and we swam in a different
direction and there were,
320
00:17:48,640 --> 00:17:51,760
I don't know, three or
four, or five, but...
321
00:17:51,840 --> 00:17:52,760
VALERIE: One of them was huge.
322
00:17:52,840 --> 00:17:54,400
HEMSWORTH: One really
big one, yeah, yeah.
323
00:17:54,480 --> 00:17:56,360
VALERIE: Yeah, biggest grey
nurse I've ever seen actually.
324
00:17:56,440 --> 00:17:58,320
HEMSWORTH: That
was the biggest grey
nurse shark you've seen?
325
00:17:58,400 --> 00:18:00,280
VALERIE: Ever.
HEMSWORTH: Oh wow.
326
00:18:00,360 --> 00:18:01,680
The big female?
327
00:18:01,760 --> 00:18:03,240
VALERIE: I think it might
have been a female actually,
328
00:18:03,320 --> 00:18:07,320
because usually
you can see the...
329
00:18:07,400 --> 00:18:08,600
male parts.
330
00:18:08,680 --> 00:18:10,960
How do you say
that on television?
331
00:18:11,440 --> 00:18:13,000
HEMSWORTH: The male parts,
that'll do.
332
00:18:13,560 --> 00:18:14,880
Bits and pieces.
333
00:18:16,040 --> 00:18:18,160
VALERIE:
Oh God Valerie, shut up.
334
00:18:18,400 --> 00:18:20,360
(laughter).
335
00:18:21,200 --> 00:18:23,520
VALERIE: I'm glad
you saw them.
336
00:18:26,920 --> 00:18:30,640
HEMSWORTH (off-screen): It's
believed there are now only
2,000 grey nurse sharks left in
337
00:18:30,720 --> 00:18:33,280
the whole
of eastern Australia...
338
00:18:35,920 --> 00:18:39,440
making this, a pretty
special encounter.
339
00:18:41,880 --> 00:18:44,560
HEMSWORTH: So that was, you
know, beyond my expectation.
340
00:18:44,640 --> 00:18:47,600
You definitely feel like this
is their space and their home,
341
00:18:47,680 --> 00:18:49,120
and you are a guest.
342
00:18:49,560 --> 00:18:52,440
It's certainly not something
that you're in control of,
343
00:18:52,760 --> 00:18:56,480
nor an environment that
you're able to manipulate,
344
00:18:56,880 --> 00:18:59,000
you know, take power over.
345
00:18:59,080 --> 00:19:02,720
You, you feel completely at
the mercy of what's around you
346
00:19:02,800 --> 00:19:04,360
with those creatures
and that situation,
347
00:19:04,440 --> 00:19:08,480
but at peace too
at the same time.
348
00:19:08,800 --> 00:19:12,000
I had no idea that I would
feel that way and have even
349
00:19:12,080 --> 00:19:15,400
more respect for the ocean
and its beautiful creatures
350
00:19:15,480 --> 00:19:17,280
that we need to protect.
351
00:19:21,520 --> 00:19:23,760
HEMSWORTH (off-screen): Like so
many other species of shark,
352
00:19:23,840 --> 00:19:25,400
the grey nurses
have been pushed to the
353
00:19:25,480 --> 00:19:27,600
brink of extinction.
354
00:19:29,800 --> 00:19:31,200
The question is,
355
00:19:31,280 --> 00:19:35,040
what can we do to turn
this huge problem around?
356
00:19:35,800 --> 00:19:37,920
And critically,
for us ocean lovers,
357
00:19:38,840 --> 00:19:42,840
are there ways we can protect
humans without harming sharks?
358
00:19:47,080 --> 00:19:49,600
HEMSWORTH: Here sharky-sharky-
sharky sharky-sharky.
359
00:19:54,080 --> 00:19:56,200
♪ ♪
360
00:19:57,800 --> 00:19:59,720
HEMSWORTH (off-screen): Sharks
are always on the move.
361
00:20:02,760 --> 00:20:04,680
Their predatory instincts
often draw them to the
362
00:20:04,760 --> 00:20:07,360
coastline to feed on
fish and marine life...
363
00:20:10,720 --> 00:20:14,120
making encounters
with us more likely.
364
00:20:19,880 --> 00:20:21,320
So for many years,
365
00:20:21,400 --> 00:20:24,160
some authorities have
set nets to capture sharks,
366
00:20:24,240 --> 00:20:26,320
to stop them reaching
popular beaches.
367
00:20:33,800 --> 00:20:36,520
But they've had
devastating consequences.
368
00:20:37,920 --> 00:20:41,000
Conservationist Val Taylor
has seen the terrible impact
369
00:20:41,080 --> 00:20:43,400
of shark nets first hand.
370
00:20:43,600 --> 00:20:46,760
VALERIE: Although
they do protect the
beach to a certain extent,
371
00:20:47,520 --> 00:20:49,800
what I dislike about them,
372
00:20:49,880 --> 00:20:54,400
well I really loathe
about them, is they bycatch.
373
00:20:54,880 --> 00:20:55,920
HEMSWORTH: Yeah.
374
00:20:56,000 --> 00:21:01,400
VALARIE: All that harmless,
beautiful marine life that
is killed.
375
00:21:01,480 --> 00:21:02,880
HEMSWORTH: So these
are some videos of animals
376
00:21:02,960 --> 00:21:04,640
being caught in the nets.
377
00:21:05,360 --> 00:21:07,160
VALERIE: Look at that,
oh it's so sad, so sad.
378
00:21:07,240 --> 00:21:08,440
HEMSWORTH: So sad, isn't it?
379
00:21:08,600 --> 00:21:10,240
VALERIE: Look, it's alive.
380
00:21:10,800 --> 00:21:11,920
HEMSWORTH:
Yeah, isn't that awful?
381
00:21:12,000 --> 00:21:13,280
VALERIE: It catches
a lot of turtles.
382
00:21:13,360 --> 00:21:15,320
HEMSWORTH: Yeah.
Wow, that's awful.
383
00:21:15,400 --> 00:21:17,000
VALERIE: Yeah, all sorts
of creatures in there.
384
00:21:17,080 --> 00:21:18,480
HEMSWORTH: Yeah.
385
00:21:18,560 --> 00:21:21,480
So these animals,
they get caught,
and then they die, right?
386
00:21:21,560 --> 00:21:26,600
VALERIE: With sharks, they
have to keep moving to aerate.
387
00:21:26,920 --> 00:21:29,720
They actually take oxygen
out of the ocean water.
388
00:21:29,800 --> 00:21:32,720
And when they're trapped
like that they can't do it.
389
00:21:32,960 --> 00:21:38,320
Ron and I made ourselves very
unpopular in our day because
390
00:21:38,400 --> 00:21:41,320
we'd go out and cut
the living animals out.
391
00:21:41,960 --> 00:21:43,240
HEMSWORTH: And free them.
VALERIE: And free them.
392
00:21:43,320 --> 00:21:44,680
I had a very good
pair of scissors.
393
00:21:44,760 --> 00:21:46,600
It's easier with the
scissors than with a knife.
394
00:21:46,680 --> 00:21:48,240
And I'd just cut them
out and free them.
395
00:21:48,800 --> 00:21:53,600
I've only ever seen
one really dangerous
shark caught in the net,
396
00:21:53,680 --> 00:21:56,440
because they can swim
under them and around them.
397
00:21:59,840 --> 00:22:03,480
HEMSWORTH (off-screen):
The impact of these nets
really is heartbreaking,
398
00:22:04,520 --> 00:22:06,160
and as Val points out,
399
00:22:06,240 --> 00:22:09,040
sharks can often swim
around them anyway.
400
00:22:10,320 --> 00:22:15,320
Thankfully, less
damaging solutions are
now starting to be used.
401
00:22:19,000 --> 00:22:21,840
To find out more,
I'm going back to shark expert
402
00:22:22,120 --> 00:22:23,640
Dr Paul Butcher.
403
00:22:24,880 --> 00:22:25,800
HEMSWORTH: Hi boys.
404
00:22:25,880 --> 00:22:27,000
PAUL: Hi Chris,
welcome on board.
405
00:22:27,080 --> 00:22:29,160
HEMSWORTH: Thank you.
406
00:22:30,040 --> 00:22:32,400
HEMSWORTH (off-screen):
Together with his team,
he wants to show me a new
407
00:22:32,480 --> 00:22:35,360
technique they're using to
keep sharks and humans apart.
408
00:22:36,880 --> 00:22:38,520
HAYDEN: Everyone holding on?
409
00:22:41,240 --> 00:22:43,800
HEMSWORTH (off-screen):
Alongside nets, parts of
Australia have used
410
00:22:43,880 --> 00:22:46,480
traps known as drumlines
to control sharks.
411
00:22:49,840 --> 00:22:52,160
Their fixed, baited
hooks catch the animals,
412
00:22:52,240 --> 00:22:54,280
which are then
simply left to die.
413
00:22:57,520 --> 00:23:00,920
But Paul's team is
pioneering a new technology,
414
00:23:01,720 --> 00:23:03,360
the smart drumline.
415
00:23:03,960 --> 00:23:08,200
So when you say
the smart drumlines versus
the previous drumlines,
416
00:23:08,280 --> 00:23:10,360
were the previous drumlines
just set up to catch them?
417
00:23:10,440 --> 00:23:13,040
PAUL: Yeah, they were
designed to catch and kill.
418
00:23:13,120 --> 00:23:15,360
They set them the day before,
check them the next day,
419
00:23:15,400 --> 00:23:17,360
so the sharks are always dead.
420
00:23:20,160 --> 00:23:21,640
HEMSWORTH (off-screen):
Over the last 50 years,
421
00:23:21,720 --> 00:23:24,000
this method has killed
over 20,000 sharks
422
00:23:24,080 --> 00:23:25,640
in Australian waters.
423
00:23:26,480 --> 00:23:28,760
PAUL: So we're just
approaching the first line.
424
00:23:29,560 --> 00:23:32,320
HEMSWORTH (off-screen):
The smart drumline
program is different.
425
00:23:32,920 --> 00:23:33,880
PAUL: Do you want
to cut a bait?
426
00:23:33,960 --> 00:23:35,880
HEMSWORTH: Yeah, sure.
427
00:23:35,960 --> 00:23:39,400
HEMSWORTH (off-screen): It's
designed to catch sharks but
then tag and release them,
428
00:23:39,720 --> 00:23:42,920
unharmed,
back to the wild.
429
00:23:43,000 --> 00:23:44,640
PAUL: Nice.
430
00:23:47,000 --> 00:23:49,520
This is what we
call the smart unit.
431
00:23:49,880 --> 00:23:53,080
When a shark takes the bait,
it triggers this magnet here,
432
00:23:53,160 --> 00:23:55,960
within 30 seconds it's
sending a signal to satellite,
433
00:23:56,040 --> 00:23:58,360
and then we get a
message on our phones.
434
00:23:58,440 --> 00:24:00,560
We get to those sharks as
quickly as we can, then tag,
435
00:24:00,640 --> 00:24:03,080
release and let
that animal go.
436
00:24:03,160 --> 00:24:05,160
Then we can just...
437
00:24:05,240 --> 00:24:06,600
HEMSWORTH:
Launch the old fish.
438
00:24:06,680 --> 00:24:08,400
PAUL: Go for it.
439
00:24:11,360 --> 00:24:13,080
HEMSWORTH: Boom.
440
00:24:13,240 --> 00:24:16,280
HEMSWORTH (off-screen):
Conservation like this
requires a strong stomach,
441
00:24:16,360 --> 00:24:18,040
which I may not have.
442
00:24:18,120 --> 00:24:19,800
HEMSWORTH: Oh, my
hands smell good.
443
00:24:19,880 --> 00:24:23,040
HEMSWORTH (off-screen):
But it's essential work.
444
00:24:23,120 --> 00:24:25,600
The tags Paul and his team
attach not only monitor
445
00:24:25,680 --> 00:24:29,640
sharks' movements,
they're also connected to
a coastal alarm system.
446
00:24:30,760 --> 00:24:32,480
That means surfers and
swimmers can be quickly
447
00:24:32,560 --> 00:24:35,000
alerted to any danger.
448
00:24:36,520 --> 00:24:38,280
PAUL: We set them just
far enough offshore,
449
00:24:38,360 --> 00:24:39,600
which is 500 meters out,
450
00:24:39,680 --> 00:24:41,880
which is pretty much just
behind the beach break,
451
00:24:41,960 --> 00:24:44,160
where we know the sharks
are travelling up and down.
452
00:24:44,240 --> 00:24:46,080
HEMSWORTH: So the smart
drumline actually acts as
453
00:24:46,160 --> 00:24:47,760
protection for the surfers.
454
00:24:47,840 --> 00:24:51,000
PAUL: Yeah, our surfers and
water uses know where they are,
455
00:24:51,080 --> 00:24:53,200
and if they're
in each day as well.
456
00:24:54,280 --> 00:24:56,080
HEMSWORTH: Launch this out.
PAUL: Yeah.
457
00:24:56,920 --> 00:24:58,680
(whistles)
458
00:24:58,760 --> 00:25:00,800
HEMSWORTH: Here,
sharky-sharky-sharky
sharky-sharky.
459
00:25:02,240 --> 00:25:04,520
HEMSWORTH (off-screen):
But as is often the case
with marine research,
460
00:25:05,120 --> 00:25:07,120
it's all a bit of
a waiting game.
461
00:25:07,720 --> 00:25:10,400
Hopefully we'll catch
one before I throw up.
462
00:25:11,320 --> 00:25:12,480
HEMSWORTH: Feeling good.
463
00:25:12,560 --> 00:25:14,000
A little seasick and
queasy for a minute there,
464
00:25:14,080 --> 00:25:15,040
but job done.
465
00:25:15,120 --> 00:25:17,840
What did we get,
23, 24 buoys in?
466
00:25:17,920 --> 00:25:19,760
I feel confident, you know,
that we've dropped enough
467
00:25:19,840 --> 00:25:22,000
drums in the water so
we'll be able to catch one
468
00:25:22,080 --> 00:25:23,640
and tag one and...
469
00:25:24,440 --> 00:25:26,440
fingers crossed.
470
00:25:26,520 --> 00:25:27,560
Thanks boys.
471
00:25:27,640 --> 00:25:29,120
I got the shark
alert on my phone.
472
00:25:29,200 --> 00:25:30,880
So looking forward
to getting a shark and we'll
473
00:25:30,960 --> 00:25:32,440
tag it and do our thing.
474
00:25:32,520 --> 00:25:33,560
PAUL: Make sure
that phone's on.
475
00:25:33,640 --> 00:25:34,960
HEMSWORTH: I will.
Thanks a lot.
476
00:25:35,040 --> 00:25:35,840
PAUL: See you mate.
477
00:25:35,920 --> 00:25:38,200
HEMSWORTH: See you guys.
478
00:25:38,600 --> 00:25:41,640
HEMSWORTH (off-screen): The use
of technology is encouraging.
479
00:25:43,280 --> 00:25:46,480
But could there be other
more traditional ways
to live with sharks?
480
00:25:47,000 --> 00:25:48,520
NICKOLLA: It's their domain,
it's their home.
481
00:25:48,600 --> 00:25:50,240
They've always been there.
482
00:25:50,320 --> 00:25:51,960
HEMSWORTH: I couldn't
agree with you more.
483
00:26:02,320 --> 00:26:04,800
HEMSWORTH (off-screen): While
I'm waiting for an alert,
484
00:26:04,880 --> 00:26:07,120
I want to find out
if there are simpler ways of
485
00:26:07,200 --> 00:26:08,520
coexisting with sharks.
486
00:26:11,840 --> 00:26:14,760
As a kid, my family and I
lived in the Northern Territory,
487
00:26:16,640 --> 00:26:19,120
in an indigenous
Australian community.
488
00:26:20,440 --> 00:26:23,640
Up there, wildlife was something
to revere and respect.
489
00:26:28,560 --> 00:26:33,160
Here on the east coast,
those same values hold true.
490
00:26:35,720 --> 00:26:37,880
NICKOLLA: I have an example
of one of my artworks here,
491
00:26:37,960 --> 00:26:40,640
which is all about country.
492
00:26:40,720 --> 00:26:41,520
It was...
493
00:26:41,840 --> 00:26:44,520
HEMSWORTH (off-screen):
Local artist Nickolla Clark
is an Arakwal
494
00:26:44,600 --> 00:26:46,360
woman of the
Bundjalung nation.
495
00:26:47,880 --> 00:26:50,080
For over 20,000 years,
her people have called the
496
00:26:50,160 --> 00:26:53,880
area around Byron Bay their
home, and have an intimate
497
00:26:53,960 --> 00:26:56,680
understanding of
both land and ocean.
498
00:26:57,840 --> 00:26:59,000
HEMSWORTH: So we're
here in Byron Bay,
499
00:26:59,080 --> 00:27:00,920
I learned to
dive at Julian Rocks.
500
00:27:01,000 --> 00:27:02,480
It's beautiful out there.
501
00:27:02,560 --> 00:27:04,480
Can you tell us the
significance of Julian Rocks
502
00:27:04,560 --> 00:27:05,960
to the Arakwal people?
503
00:27:06,040 --> 00:27:08,120
NICKOLLA: It's a significant
site to us, where our creator,
504
00:27:08,200 --> 00:27:09,440
where he lays rest.
505
00:27:09,520 --> 00:27:11,320
So we don't go
on Julian Rocks,
506
00:27:11,400 --> 00:27:12,520
we don't harm it,
507
00:27:12,600 --> 00:27:14,120
we don't touch it,
so it's pretty important.
508
00:27:14,200 --> 00:27:15,400
HEMSWORTH: Yeah.
509
00:27:15,480 --> 00:27:16,800
Do the Arakwal people
have a big connection
510
00:27:16,880 --> 00:27:17,960
the ocean specifically?
511
00:27:18,040 --> 00:27:19,160
NICKOLLA: Yeah,
so we're coastal people.
512
00:27:19,240 --> 00:27:20,800
For us, living so
close to the beach,
513
00:27:20,920 --> 00:27:24,360
collecting bush foods and
having the ocean to swim and
514
00:27:24,440 --> 00:27:27,240
play, and we would
live off the sea.
515
00:27:27,320 --> 00:27:29,040
HEMSWORTH: Have you
noticed more activity with
516
00:27:29,120 --> 00:27:30,560
sharks in particular?
517
00:27:30,640 --> 00:27:32,840
NICKOLLA: There's definitely
been an increase in activity
518
00:27:32,920 --> 00:27:35,840
between people and the ocean,
and sharks in particular.
519
00:27:36,280 --> 00:27:39,520
And a lot of the places people
actually go here on country is
520
00:27:39,600 --> 00:27:41,080
they go to these
beautiful beaches,
521
00:27:41,160 --> 00:27:43,640
right next to rocky
outcrops where sharks nest.
522
00:27:45,720 --> 00:27:47,280
It's their domain,
it's their home.
523
00:27:47,360 --> 00:27:49,440
They've always been there.
524
00:27:50,400 --> 00:27:52,960
HEMSWORTH (off-screen):
Over generations, the
Arakwal people have gained
525
00:27:53,040 --> 00:27:56,240
a detailed knowledge about when
and where to avoid going in
526
00:27:56,320 --> 00:27:58,160
the water to stay safe.
527
00:27:59,480 --> 00:28:00,680
NICKOLLA: Here in Byron Bay,
528
00:28:00,760 --> 00:28:01,960
it's really visible to
see when they're feeding,
529
00:28:02,040 --> 00:28:03,640
when there's feeding
frenzies going on.
530
00:28:03,720 --> 00:28:07,000
Traditionally in winter
we wouldn't swim further
than your knee height,
531
00:28:07,600 --> 00:28:09,400
sharks are more active then.
532
00:28:09,480 --> 00:28:11,160
That is a cultural
signifier we'd have,
533
00:28:11,240 --> 00:28:13,480
so coexisting is
really important.
534
00:28:13,560 --> 00:28:14,600
Like if we want to be here,
535
00:28:14,680 --> 00:28:15,880
we're going
to have to do that.
536
00:28:15,960 --> 00:28:17,800
HEMSWORTH: Yeah, I couldn't
agree with you more.
537
00:28:19,640 --> 00:28:21,400
HEMSWORTH (off-screen):
This ancient wisdom,
538
00:28:21,480 --> 00:28:22,760
coupled with
humane technologies,
539
00:28:23,760 --> 00:28:26,440
offers a way to
coexist with sharks,
540
00:28:26,520 --> 00:28:28,720
close to our shores.
541
00:28:31,920 --> 00:28:34,840
Unfortunately, the problems
facing sharks around the world
542
00:28:34,920 --> 00:28:37,840
are often more complex,
and more serious.
543
00:28:44,560 --> 00:28:46,000
Over the last 50 years,
544
00:28:46,840 --> 00:28:49,320
there's been a 70%
drop in the number of sharks
545
00:28:49,400 --> 00:28:52,040
in the world's oceans.
546
00:28:55,200 --> 00:28:58,760
The cause is our
over-exploitation of the sea,
547
00:29:02,080 --> 00:29:04,400
and the slaughter of tens
of millions of sharks,
548
00:29:04,920 --> 00:29:06,920
simply for their fins.
549
00:29:11,200 --> 00:29:15,040
The reality is these beautiful
animals have got more to fear
550
00:29:15,120 --> 00:29:18,200
from us than we do from them.
551
00:29:18,760 --> 00:29:21,000
I think like everybody who
spends time in the ocean,
552
00:29:21,080 --> 00:29:25,560
I've had the fear of sharks
at times, and shark attacks,
553
00:29:25,640 --> 00:29:29,800
and talking to people who
have been very close or been
554
00:29:29,920 --> 00:29:31,640
involved in an attack.
555
00:29:31,720 --> 00:29:33,520
It certainly makes
it even more real.
556
00:29:33,600 --> 00:29:36,400
I think we should have a
healthy respect for sharks,
557
00:29:36,480 --> 00:29:41,200
and how dangerous they
can be, but realize that
we are in their environment,
558
00:29:41,280 --> 00:29:45,080
and what's more scary is
an ocean without sharks.
559
00:29:52,880 --> 00:29:55,080
There's been an alert from
one of the smart drumlines.
560
00:29:57,120 --> 00:29:59,080
It means something's
taken the bait.
561
00:30:05,240 --> 00:30:11,120
Hopefully it'll be a chance
to help with some shark
conservation and also,
562
00:30:11,480 --> 00:30:14,000
meet a great white
face to face.
563
00:30:14,080 --> 00:30:15,520
Is this exciting for you?
564
00:30:15,600 --> 00:30:17,000
HAYDEN: It's always
exciting for me.
565
00:30:17,560 --> 00:30:20,000
It's the thrill of fishing
and not knowing what's going
566
00:30:20,080 --> 00:30:21,320
to be on the
other end of the line.
567
00:30:21,400 --> 00:30:23,880
HEMSWORTH: Yeah, right.
It could be a jet ski.
568
00:30:24,600 --> 00:30:26,000
HAYDEN: You'd hope not.
569
00:30:26,320 --> 00:30:28,200
HEMSWORTH: It'll be my
first time handling a shark.
570
00:30:28,280 --> 00:30:31,520
PAUL: You're the number one
man today, so yeah, shark 101,
571
00:30:31,600 --> 00:30:32,840
you're going to be
out there tagging.
572
00:30:33,200 --> 00:30:35,040
HEMSWORTH: Put it in a
headlock and I'll get the tail?
573
00:30:35,120 --> 00:30:37,080
(laughter).
574
00:30:39,720 --> 00:30:41,400
HEMSWORTH (off-screen):
But as soon as we arrive,
575
00:30:41,480 --> 00:30:43,800
it's clear
something's not right.
576
00:30:44,080 --> 00:30:46,160
HAYDEN: We just look for
movement in the back bubble.
577
00:30:47,640 --> 00:30:49,680
And when there's shark on,
578
00:30:49,760 --> 00:30:51,960
they'll swim from
side to side sometimes.
579
00:30:52,040 --> 00:30:54,760
And to me, that's laying
there with the wind.
580
00:30:55,640 --> 00:30:59,560
PAUL: If you want to grab that
bungee Chris and pull it in.
581
00:31:03,800 --> 00:31:05,440
HEMSWORTH: Oh, where's
my fish that I baited up?
582
00:31:05,520 --> 00:31:08,920
PAUL: Bait's gone,
so yeah, good signs
but not what we wanted.
583
00:31:09,000 --> 00:31:12,400
So to lose a full bait, we
rarely have that happen.
584
00:31:12,480 --> 00:31:13,800
HEMSWORTH: Do you reckon it
might have something to do
585
00:31:13,880 --> 00:31:14,920
with the person who baited it?
586
00:31:15,000 --> 00:31:16,120
PAUL: Oh, not at all.
587
00:31:16,200 --> 00:31:19,000
So let's get this
baited up again.
588
00:31:19,800 --> 00:31:21,480
HEMSWORTH (off-screen):
It's disappointing.
589
00:31:23,400 --> 00:31:26,720
But it's not yet game over.
590
00:31:27,960 --> 00:31:30,120
PAUL: Throw it in there.
591
00:31:30,200 --> 00:31:33,680
HEMSWORTH (off-screen):
Hopefully we can tag one
before the end of the day.
592
00:31:40,000 --> 00:31:42,200
CHARLIE: Okay guys,
the trial can start now.
593
00:31:42,280 --> 00:31:44,680
HEMSWORTH (off-screen):
In the meantime, I want
to find out how we can
594
00:31:44,760 --> 00:31:47,640
protect ourselves if
a shark does attack.
595
00:31:53,720 --> 00:31:55,680
I think it's fair to say,
596
00:31:55,760 --> 00:31:59,280
however good we
get at keeping humans and
sharks apart in the ocean,
597
00:32:00,680 --> 00:32:03,080
there will always
be moments when we meet.
598
00:32:06,120 --> 00:32:09,680
And in those worst case
scenarios, when sharks bite,
599
00:32:09,760 --> 00:32:12,760
is there anything
that can be done?
600
00:32:13,480 --> 00:32:16,080
Charlie Huveneers is a
scientist who's thought more
601
00:32:16,160 --> 00:32:17,720
about this than most.
602
00:32:17,800 --> 00:32:19,080
Hey mate, how are you?
603
00:32:19,440 --> 00:32:21,000
CHARLIE (over computer):
Not too bad, thanks.
604
00:32:21,080 --> 00:32:23,080
HEMSWORTH (off-screen):
For several years he's
been looking at ways of
605
00:32:23,160 --> 00:32:25,400
deterring sharks that
decide to attack.
606
00:32:26,640 --> 00:32:31,440
Is your research and line of
work due to your passion and
607
00:32:31,520 --> 00:32:33,960
love for sharks, or passion
and love for humans,
608
00:32:34,400 --> 00:32:36,120
or who are you?
609
00:32:36,200 --> 00:32:37,680
Who are you more invested in?
610
00:32:37,760 --> 00:32:40,320
It's okay to say
the sharks too.
611
00:32:41,400 --> 00:32:43,080
CHARLIE (over computer):
It depends in what
situations, but yeah,
612
00:32:43,160 --> 00:32:44,520
it's a combination.
613
00:32:44,600 --> 00:32:46,200
It's really, I've always
been interested in sharks,
614
00:32:46,280 --> 00:32:47,720
since I was a kid.
615
00:32:47,800 --> 00:32:50,240
But yeah, the fascination for
sharks just changed into a
616
00:32:50,320 --> 00:32:54,400
real interest in the science
and understanding the sharks
617
00:32:54,480 --> 00:32:56,720
better, so that we can
actually help in providing a
618
00:32:56,800 --> 00:33:00,080
safer environment, for
people but also for sharks.
619
00:33:00,160 --> 00:33:02,160
HEMSWORTH: Yeah, are you
going into the field soon
620
00:33:02,240 --> 00:33:04,000
to test any of those deterrents?
621
00:33:04,080 --> 00:33:06,120
CHARLIE (over computer): Yeah,
actually we're going next week.
622
00:33:06,200 --> 00:33:07,080
HEMSWORTH: Well
good luck with it.
623
00:33:07,160 --> 00:33:08,880
CHARLIE (over computer): Thanks.
624
00:33:10,880 --> 00:33:14,080
HEMSWORTH (off-screen): Charlie
and his colleagues from Flinders
University in Adelaide
625
00:33:14,160 --> 00:33:16,640
are heading into the
seas off south Australia.
626
00:33:19,440 --> 00:33:21,760
On board they're testing the
latest shark deterrent and
627
00:33:21,840 --> 00:33:23,400
protection technologies.
628
00:33:24,480 --> 00:33:27,480
CHARLIE: So what we've seen in
that in recent years there has
629
00:33:27,720 --> 00:33:30,800
been an increase in the number
of shark bites globally,
630
00:33:31,160 --> 00:33:34,320
including in Australia, and
this has resulted in a lot of
631
00:33:34,400 --> 00:33:37,640
interest in the devices to
try to reduce those risks.
632
00:33:47,240 --> 00:33:49,680
HEMSWORTH (off-screen):
The team have sailed to
the Neptune Islands,
633
00:33:49,760 --> 00:33:52,120
a hot spot for great whites.
634
00:33:53,480 --> 00:33:56,280
The sharks come here to prey
on Australia's largest colony
635
00:33:56,360 --> 00:33:58,160
of long-nosed fur seals.
636
00:34:00,760 --> 00:34:03,600
So it's the perfect place to
test products designed to take
637
00:34:03,680 --> 00:34:06,560
advantage of sharks'
very unusual senses.
638
00:34:08,040 --> 00:34:10,080
CHARLIE: There's only a small
number of animals that have
639
00:34:10,160 --> 00:34:12,280
this ability to
detect electric field,
640
00:34:13,000 --> 00:34:15,080
and sharks have it through
these black dots called
641
00:34:15,160 --> 00:34:16,800
Ampullae of Lorenzini.
642
00:34:16,880 --> 00:34:20,560
The idea behind these electric
field based deterrents is that
643
00:34:20,640 --> 00:34:23,520
they will produce
such a strong pulse,
644
00:34:23,600 --> 00:34:27,560
that it will overwhelm this
sensory organ and make the
645
00:34:27,640 --> 00:34:29,760
shark physically move
away from the source.
646
00:34:31,640 --> 00:34:35,240
HEMSWORTH (off-screen): The aim
is to develop a safer surfboard,
647
00:34:35,320 --> 00:34:37,680
with an electrical shark
deterrent built into it.
648
00:34:39,200 --> 00:34:42,920
CHARLIE: This produces an
electric field through two
649
00:34:43,000 --> 00:34:46,800
electrodes which
are positioned just
underneath the board,
650
00:34:46,880 --> 00:34:48,920
and this is kind of
a replica of a surfboard.
651
00:34:49,480 --> 00:34:53,120
This has produced a
field which is transmitted
to these electrodes,
652
00:34:53,200 --> 00:34:56,320
and creates a bit of a
barrier around the surfboard,
653
00:34:56,400 --> 00:34:59,200
which is theory should
be deterring the sharks.
654
00:35:01,560 --> 00:35:03,160
HEMSWORTH (off-screen):
To test the theory,
655
00:35:03,240 --> 00:35:05,840
the experiment compares
a shark's reactions to a
656
00:35:05,920 --> 00:35:09,200
board with the electrical
device switched on,
657
00:35:09,280 --> 00:35:12,080
to a board with it off.
658
00:35:13,480 --> 00:35:16,360
But getting robust data
means repeating the process
659
00:35:16,920 --> 00:35:18,760
many times over.
660
00:35:27,640 --> 00:35:29,640
Over hundreds of
previous trials,
661
00:35:29,720 --> 00:35:31,640
the team have
captured remarkable footage
662
00:35:31,720 --> 00:35:33,480
of sharks in action.
663
00:35:33,880 --> 00:35:35,080
MAN: Oh!
664
00:35:37,400 --> 00:35:38,880
HEMSWORTH (off-screen): First
they recorded what happened to a
665
00:35:38,920 --> 00:35:41,160
baited board with a
device turned off.
666
00:35:42,520 --> 00:35:44,520
CHARLIE: It's interesting
that we do have a bait just
667
00:35:44,600 --> 00:35:45,840
underneath that board.
668
00:35:45,920 --> 00:35:47,360
MADDIE: It's swimming as
we would expect to see it
669
00:35:47,440 --> 00:35:50,040
swimming around a bait.
670
00:35:55,080 --> 00:35:56,720
HEMSWORTH (off-screen): And then
what happened to the sharks when
671
00:35:56,800 --> 00:35:58,640
the device was turned on.
672
00:36:01,640 --> 00:36:02,640
CHARLIE: Look at it.
673
00:36:02,720 --> 00:36:05,160
MADDIE: So that was a
pretty obvious flinch.
674
00:36:05,240 --> 00:36:06,680
CHARLIE: He's coming back now.
675
00:36:08,480 --> 00:36:10,160
That kind of
flinch or reaction,
676
00:36:10,240 --> 00:36:13,120
we didn't see that when the
deterrent was turned off.
677
00:36:16,880 --> 00:36:19,080
MADDIE: And you can see the
really obvious flinching in
678
00:36:19,160 --> 00:36:20,640
the gills as well,
and the jaw gaping.
679
00:36:25,320 --> 00:36:26,400
CHARLIE: Oh look at that one,
680
00:36:26,480 --> 00:36:27,880
so that one came
really from down below,
681
00:36:27,960 --> 00:36:30,560
it was only within half a meter.
682
00:36:31,880 --> 00:36:35,160
Overall there was a 60%
reduction in the proportion of
683
00:36:35,240 --> 00:36:37,840
bait being taken, so 60%
reduction in shark bites.
684
00:36:41,800 --> 00:36:43,920
HEMSWORTH (off-screen):
If the eight people killed
by sharks in Australia
685
00:36:44,000 --> 00:36:47,520
in 2020 had been
able to use an electric
deterrent like this,
686
00:36:48,320 --> 00:36:50,520
then five may still be alive.
687
00:36:54,440 --> 00:36:57,800
Products like these
are promising,
688
00:36:57,880 --> 00:37:00,600
as we may be able to reduce
fatalities in the future,
689
00:37:00,680 --> 00:37:03,320
all without harming the sharks.
690
00:37:04,840 --> 00:37:05,840
Meanwhile...
691
00:37:05,920 --> 00:37:07,400
PAUL: Oh, there's
something on there.
692
00:37:07,480 --> 00:37:09,600
HEMSWORTH (off-screen):
Will I finally get my chance
to come face to face
693
00:37:09,680 --> 00:37:11,240
with a great white?
694
00:37:11,960 --> 00:37:13,600
Oh wow.
695
00:37:16,280 --> 00:37:19,440
HEMSWORTH: Okay, I just
got a text message, PVC 276,
696
00:37:19,520 --> 00:37:22,040
I assume that's the buoy
number or the coordinates,
697
00:37:22,160 --> 00:37:23,680
and looks like
we have a shark.
698
00:37:23,840 --> 00:37:25,240
So let's go and check it out.
699
00:37:26,560 --> 00:37:28,840
HEMSWORTH (off-screen):
My journey to understand
how sharks and humans
700
00:37:28,920 --> 00:37:31,200
can live together
has been eye-opening.
701
00:37:32,320 --> 00:37:34,360
HEMSWORTH: Alright boys?
Are we on or what?
702
00:37:34,440 --> 00:37:36,320
PAUL: Yes, it
looks like we're on.
703
00:37:36,400 --> 00:37:37,280
Good?
704
00:37:37,360 --> 00:37:39,040
HEMSWORTH: Do it.
705
00:37:41,280 --> 00:37:44,320
HEMSWORTH (off-screen):
But I still haven't seen a
great white shark up close.
706
00:37:45,680 --> 00:37:47,120
HEMSWORTH: Here we go.
707
00:37:54,160 --> 00:37:56,840
So we obviously have no idea
what kind of shark it is.
708
00:37:56,920 --> 00:37:59,640
PAUL: No, but what
we do know is that usually
709
00:37:59,720 --> 00:38:02,240
those buoys that go
off south of the river,
710
00:38:02,320 --> 00:38:05,080
it's usually a
white shark, so it's...
711
00:38:05,160 --> 00:38:07,200
Yeah, we've got our
fingers crossed.
712
00:38:10,320 --> 00:38:13,440
HEMSWORTH (off-screen): We reach
the smart drumline location.
713
00:38:16,720 --> 00:38:19,720
And this time, the
buoys don't seem to be just
714
00:38:19,800 --> 00:38:21,840
drifting with the wind.
715
00:38:22,600 --> 00:38:24,320
PAUL: Now we've got the buoys
together, they're tangled,
716
00:38:24,400 --> 00:38:26,280
the buoy's
bouncing up and down.
717
00:38:26,360 --> 00:38:28,480
Rest assured there's
a shark on this one.
718
00:38:28,800 --> 00:38:29,960
HAYDEN: Alright Paul,
you alright Chris?
719
00:38:30,040 --> 00:38:31,960
PAUL: Yeah, go ahead.
720
00:38:32,040 --> 00:38:34,160
Well there's
something on there.
721
00:38:35,560 --> 00:38:36,760
Oh, it's a big white.
722
00:38:37,480 --> 00:38:38,720
A huge white.
723
00:38:38,800 --> 00:38:40,320
Big white.
724
00:38:44,840 --> 00:38:46,120
Come in here Chris.
725
00:38:46,200 --> 00:38:48,120
HEMSWORTH: Oh wow.
726
00:38:49,080 --> 00:38:50,600
Wow.
727
00:38:50,920 --> 00:38:52,520
HEMSWORTH (off-screen): To limit
the stress on the shark,
728
00:38:52,600 --> 00:38:54,640
the team must work
as fast as possible.
729
00:38:55,920 --> 00:38:57,440
PAUL: You can lift his head?
730
00:38:57,520 --> 00:38:59,640
HEMSWORTH (off-screen):
They need to turn the
shark onto its back,
731
00:39:00,600 --> 00:39:03,040
which puts it into
a peaceful state.
732
00:39:09,400 --> 00:39:11,920
The hook may look gruesome,
but the team need to use it to
733
00:39:12,000 --> 00:39:14,480
stabilize the shark's
head alongside the boat.
734
00:39:19,520 --> 00:39:22,280
HEMSWORTH: How big is that,
two and a half meters?
735
00:39:22,360 --> 00:39:23,600
PAUL: Yeah, 2.6, 2.8?
736
00:39:23,680 --> 00:39:25,520
HEMSWORTH: 2.6, 2.8.
737
00:39:26,760 --> 00:39:30,080
And this is safe and mostly
harmless for the shark, right?
738
00:39:30,160 --> 00:39:31,040
PAUL: That's right.
739
00:39:31,120 --> 00:39:33,400
We've done a lot of research,
especially with great white
740
00:39:33,480 --> 00:39:36,000
sharks now, through a process
of taking blood out of them.
741
00:39:36,080 --> 00:39:38,200
So basically it doesn't
stress the animal out.
742
00:39:39,680 --> 00:39:42,040
HEMSWORTH: It's comforting to
know it's not hurting the shark.
743
00:39:42,120 --> 00:39:44,200
The guys have reassured me
it's pretty docile at this
744
00:39:44,280 --> 00:39:46,360
point and you know,
very little harm,
745
00:39:46,680 --> 00:39:51,080
and so I've seen plenty of
movies and imagery of them,
746
00:39:51,560 --> 00:39:54,560
but never this, up close
in person and, yeah,
747
00:39:54,640 --> 00:39:56,280
just amazing.
748
00:39:58,000 --> 00:39:59,680
PAUL: Male.
749
00:40:00,760 --> 00:40:04,480
HEMSWORTH (off-screen): We
record as much information as
possible in the time available.
750
00:40:05,960 --> 00:40:09,880
PAUL: Alright, Hayden, 2-8-1.
751
00:40:09,960 --> 00:40:11,600
HAYDEN: 2-8-1.
752
00:40:15,680 --> 00:40:17,720
HEMSWORTH (off-screen):
Each measurement revealing
something different
753
00:40:17,800 --> 00:40:20,120
about its life and history.
754
00:40:20,680 --> 00:40:21,880
PAUL: The tiny little fin clip,
755
00:40:21,960 --> 00:40:23,960
that'll get divided up
into six different pieces,
756
00:40:24,040 --> 00:40:26,480
one sample will go to one lab,
another sample to another.
757
00:40:26,560 --> 00:40:28,680
We want to know how many
sharks there are in the
758
00:40:28,760 --> 00:40:31,280
population, who their
mums and dads are,
759
00:40:31,360 --> 00:40:32,800
who their brothers
and sisters are.
760
00:40:32,920 --> 00:40:35,280
So next part of
the process is working out
761
00:40:35,360 --> 00:40:37,120
what they're eating.
762
00:40:37,200 --> 00:40:40,400
We take a DNA sample from
around its butt basically.
763
00:40:40,480 --> 00:40:41,560
HEMSWORTH: And here we are,
764
00:40:41,640 --> 00:40:44,000
about to take an
anal swab from a shark.
765
00:40:44,080 --> 00:40:45,400
All for science.
766
00:40:45,480 --> 00:40:48,440
So let's dig in, shall we?
767
00:40:50,520 --> 00:40:52,720
Where is its butt?
768
00:40:53,040 --> 00:40:56,000
HEMSWORTH (off-screen):
Knowing a shark's diet can
give vital clues about
769
00:40:56,080 --> 00:40:57,840
how and where it feeds,
770
00:40:58,280 --> 00:41:00,800
helping us understand
its life underwater.
771
00:41:01,200 --> 00:41:02,960
Sorry about that mate.
772
00:41:04,800 --> 00:41:06,880
To monitor this
shark in real time,
773
00:41:06,960 --> 00:41:09,560
an acoustic transmitter
tag is then attached.
774
00:41:09,640 --> 00:41:10,640
Are you alright there?
775
00:41:10,720 --> 00:41:11,560
Everyone alright?
776
00:41:11,640 --> 00:41:12,880
PAUL: Yeah.
777
00:41:13,720 --> 00:41:15,480
HEMSWORTH (off-screen): Meaning
its movements can be tracked for
778
00:41:15,560 --> 00:41:17,880
up to 10 years.
779
00:41:18,280 --> 00:41:19,480
PAUL: See, just
a quick incision,
780
00:41:19,560 --> 00:41:21,480
shark doesn't even know.
781
00:41:22,840 --> 00:41:24,400
HEMSWORTH (off-screen):
With the science wrapped up,
782
00:41:24,480 --> 00:41:26,280
it's time to let the shark go.
783
00:41:27,640 --> 00:41:28,640
Alright.
784
00:41:28,720 --> 00:41:29,960
PAUL: Alright guys,
let's do this.
785
00:41:30,040 --> 00:41:31,360
HEMSWORTH: So you're
going to hold the dorsal
while you're doing it?
786
00:41:31,440 --> 00:41:32,440
PAUL: Just hold that Chris.
787
00:41:32,520 --> 00:41:33,560
HEMSWORTH: Yep.
788
00:41:33,640 --> 00:41:34,840
PAUL: And I'm just going
to let that go there,
789
00:41:34,880 --> 00:41:36,760
and we're going to
wait for him to kick.
790
00:41:37,440 --> 00:41:38,880
And then we, when
he goes the other way,
791
00:41:38,960 --> 00:41:40,000
we'll let him go.
792
00:41:40,080 --> 00:41:41,240
HAYDEN: There he goes,
he wants to swim.
793
00:41:41,320 --> 00:41:42,560
HEMSWORTH: Let him go?
794
00:41:49,000 --> 00:41:51,120
PAUL: There he goes,
out the front of the boat,
795
00:41:51,200 --> 00:41:55,720
straight to New Zealand.
796
00:41:58,240 --> 00:42:01,720
HEMSWORTH: He cruised
off pretty gently, huh?
797
00:42:04,000 --> 00:42:05,920
HEMSWORTH (off-screen): The
great white is now one of over
798
00:42:06,000 --> 00:42:08,160
400 in the monitoring program.
799
00:42:08,240 --> 00:42:11,240
If any come within half
a mile of the shore,
800
00:42:11,320 --> 00:42:13,280
their tags will
trigger an alarm,
801
00:42:13,360 --> 00:42:15,280
allowing the water
to be evacuated,
802
00:42:17,160 --> 00:42:19,640
keeping swimmers
and surfers safe.
803
00:42:22,600 --> 00:42:24,720
What's more,
having been tagged,
804
00:42:24,800 --> 00:42:26,880
it turns out the shark's
then likely to avoid this
805
00:42:26,960 --> 00:42:28,600
spot for quite a while.
806
00:42:30,360 --> 00:42:32,560
PAUL: We do know from our
satellite tag work that the
807
00:42:32,640 --> 00:42:34,840
next day its 15 to 30
kilometers offshore,
808
00:42:34,920 --> 00:42:38,440
so not only have we taken
it away from the direct beach,
809
00:42:38,520 --> 00:42:40,800
you can see the waves
breaking only 100 meters
810
00:42:40,880 --> 00:42:41,920
away from us, so it's...
811
00:42:42,000 --> 00:42:43,280
HEMSWORTH: I've surfed
there a few times.
812
00:42:43,440 --> 00:42:45,520
PAUL: Surfing in there,
he's released, he's off,
813
00:42:45,600 --> 00:42:48,320
so the smart drumlines have
done their bit for the day.
814
00:42:48,720 --> 00:42:49,520
HEMSWORTH: Great.
815
00:42:49,600 --> 00:42:50,480
PAUL: Well done
on your first shark.
816
00:42:50,560 --> 00:42:51,880
HEMSWORTH: Success, thank you.
817
00:42:51,960 --> 00:42:53,800
HAYDEN: Thank you.
HEMSWORTH: Cheers guys.
818
00:43:02,520 --> 00:43:05,560
HEMSWORTH (off-screen): Meeting
the largest predatory shark in
the ocean has been an
819
00:43:05,640 --> 00:43:07,320
eye-opener for sure.
820
00:43:12,600 --> 00:43:15,960
It's made me realize that
despite their ability to harm,
821
00:43:16,080 --> 00:43:18,400
these are deeply
vulnerable creatures.
822
00:43:20,720 --> 00:43:24,200
Thankfully, we're
now learning how to
better live together.
823
00:43:25,200 --> 00:43:27,200
And I think when
we're enjoying the ocean,
824
00:43:27,280 --> 00:43:30,960
we should never forget
that we are the visitors
825
00:43:31,040 --> 00:43:32,800
to their home.
826
00:43:34,480 --> 00:43:37,120
I think I have a greater
understanding of how fragile
827
00:43:38,120 --> 00:43:42,880
the ocean is, and the
devastating effect we can have
828
00:43:42,960 --> 00:43:45,800
on it, and also the positive
effects we can have on it,
829
00:43:45,880 --> 00:43:48,120
depending on what road
we choose to take.
830
00:43:48,200 --> 00:43:49,800
DIRECTOR (off-screen): Are you
going to give up surfing?
831
00:43:49,880 --> 00:43:51,440
HEMSWORTH: Definitely not.
