All right.

There's his head in.

An animal this size is well and truly capable of taking a human, any size human, but this particular one, we've been getting reports saying that that's been following quite closely behind boats, and it's been going up onto the boat ramp itself, so it's just sort of getting to that stage where it's a significant risk where we've got to deal with it.

[ Crocodile hisses ] -Matt needs to secure the world's most powerful jaws.

A big male salty like this one can out-chomp a great white shark.

Once a cable tie forces the jaws closed, the croc is disarmed.

-Spot-on there, I'm happy with that.

Probably what we'll do now is effectively get the croc onto the boat, so it's secure, so what we need to do is run this rope out the end of the trap and through to the boat, and then we can pull the animal in.

Could be interesting.

-Now it's the sheer weight of the animal the rangers are fighting.

♪♪ -Well, he didn't have much fight in him at the start of the exercise, but he's certainly got it now.

It's commonly called the death roll.

It's a move that they do when they're taking prey, but also is a defensive move.

-They have to get 800 pounds of croc onboard without falling in the drink themselves.

-You definitely got to respect them.

They have a lot of power.

All right.

♪♪ ♪♪ I'll get you to jump on and help peel him back.

-Ready?

-Yep.

Ready?

One, two, three.

Go.

Steady.

-Since croc hunting was banned 40 years ago, the population has gone from near extinct to abundant, which means more heavy lifting for rangers.

-This back one is purely to cover the eyes, which calms the animal down considerably.

♪♪ -Happy?

-Happy.

You happy?

On your count.

-One, two, three.

-It's a feat of will for two men to get one of the largest living reptiles on deck.

-One, two, three.

[ Both grunting ] ♪♪ ♪♪ -All right.

That's a big animal.

-The croc will travel south to the area's only reptile park in Broome, a grueling 12-hour overnight drive.

-I reckon if we give him Valium now, then when you have to unload, get him off of... -The local vet, who's used to dealing with Australian wildlife, meets them en route.

-So what we're going to do is we're going to give him some Valium, relaxes his brain as well as his muscles, so helps him not be so stressed.

Little brave mate, good on you.

Well, I've done 25 years in the Kimberley, so we've been privileged enough to treat a few crocodiles, and in fact, I've treated a Komodo dragon that used to be at the croc farm here and that, so we've been very privileged to treat some of these big, beautiful creatures.

They're magnificent souls.

-News of the great croc's capture travels fast.

-The big one from the port?

[ Indistinct conversations ] -These old souls hold a special place in the hearts of the locals.

-I seen the crocodile when he's a baby.

He used to come up, right up to us, you know, but we couldn't pet him, you know, like wildlife and not like a pussycat or a dog, but at least you can chuck him the leftovers.

Yeah.

We've seen it grow, grow, grow, grow.

Yeah, and that's him there, dear old thing.

I love them.

Yeah.

I'll never forget him.

♪♪ -The Wyndham croc has a long trip ahead, but once that's behind him, he'll live out his days as a stud in the croc park.

Life could be worse.

[ Birds chirping ] -I certainly respect them.

-Might have jumped on top of one once.

Whoa.

Hey, that's how we used to catch them in the old days.

The old croc handlers, you'd just drift down the creek at night -- Eerie, it was -- with the spotlight.

Sneak up, paddle up beside him and take a big breath, and then you just grab him, grab him around the nose, and then you'd stick your fingers in his nostrils there on top of his snout, reel him in as far as you could and hang on for dear life.

-The Australian Outback, full of tall tales.

Next time on "Outback," it's the dry season, so there's cattle to muster, and Kimberley's best cowboys hit the dust.

-Too old for this.

Yeah.

-Off the coast, humans and whales have a close encounter.

-Pretty much like a steam train.

It'll just rip you straight up off the bottom.

-And Mandy and her roos go bush.

-586 roos we've released now, and it doesn't get any easier.
