Freshwater Crocodiles Discovering New Territory | Out There With Jack Randall

[music playing]

Aha!

Sitting up on the bank

Ah, yeah

They are

They're all over the place

CHARLIE MANOLIS: One,
two, three, four, five–

– Yeah, and one in the water
– And there's one in the water

Six

JACK RANDALL: We've finally
managed to find where

the freshwater crocs
have been hiding

from their
cannibalistic cousins–

the salties

Now, they might look small,
these freshwater crocodiles,

but don't be fooled

They've still got
an unbelievable jaw

pressure and very sharp teeth

So if we got bitten by
one, we would certainly

be in hospital–
stitches, maybe worse

[music playing]

There's so many
in his little hole

that you'd run the risk
of standing on one

We've just got to
be super careful

Catching crocs

Oy, this is a bit of a–
this is how you do it

Pretty much the only
way of getting them

We know there's a croc
in here somewhere

Oh!

Okay

We got one

CHARLIE MANOLIS:
We got him here

His head's loose, Jack

You're at the bitey end

Okay

Ah!

Yes

I got him

Wow, they're actually
unbelievably strong,

these crocodiles

You wouldn't believe it

Even at this size

CHARLIE MANOLIS: You got it?
– Oh, yeah

Excellent

What a beauty

Look at that

Freshwater crocodile

You can see how they're
different to the salties,

with that narrower snout

The salties have
that broad snout

They're not as
aggressive as the salty

These guys are still
really, really strong

OK, let's get him out here

This is the times of catching
crocodiles to do these surveys

You have to do this

You get these nets in and catch
crocodiles by hand like this

Wow

What a thrill

CHARLIE MANOLIS:
Just tie it off

JACK RANDALL:
Literally on the top

CHARLIE MANOLIS: Yep, yep

Now we've got it secure,
We need our gray tape

Ah, ah, ah, ah,
ah, ah, ah, ah, ah

And roll it around like that

That's it

This is going to quiet
him down a fair bit

Two, two, three

JACK RANDALL: We're
collecting the data

that we really need
to work out what

is happening to these guys–

Over

JACK RANDALL: Because
they're being pushed away

out of their usual habitat

CHARLIE MANOLIS: So it's
three nails, two without

JACK RANDALL: And
they're going to be

pushed into these
little waterholes

where there's less food

CHARLIE MANOLIS: Tether him

JACK RANDALL: We'll just leave
them all in this river bank

until we're ready
to release them

Back to work

[music playing]

Wow, that's a big one

Whoo!

Oh, we've got one
on this side too

OK, we got a lot

[groaning]

That's a noise from a freshy

They make that vocalization

They do that when they're
panicking, hoping that the mom

would come back– normally when
they're much smaller than this

[groaning]

There's crocs
everywhere in here

This one's a bit heavier
than the other one, Charlie

[music playing]

Well, this is it

This is the last croc

We had nine crocs, and
out of all of those,

seven were female, two male

That's good news

The males can breed
with the females

Just under six feet

The bad news?

Who knows how long it would
take for a massive salty

to invade this billabong?

Off you go, mate

Whoa!

Whoo!

[music playing]

We need to figure out how
the salties are working

their way into new territory
