Natural World: Invasion of the Crocodiles (12 of 23)

Invasion of the Crocodiles

If this crocodile keeps moving west, he'll end up in Darwin Harbour.
Then he'll be a problem crocodile.
In a five-kilometre stretch, Adam spots ten more crocodiles.
There's another one.
I'm actually amazed how many crocodiles are out here.
They're all over the place.
It 's an unexpected result.
It not only confirms that the Mary River crocodiles are pushing into the sea but they're doing so in huge numbers.
I'm really stoked by all this.

We've got some fantastic data.
To see so many out here is just fantastic.
It tells us a huge amount about the populations of crocs in these rivers.
It 's strong evidence that the Mary River is now full.
But where are the crocodiles going?
Parks and wildlife rangers have had a busy start to the year, catching 19 crocodiles in the last month alone.
Saltwater crocodile numbers are at an all-time high.
Last year, rangers pulled 253 crocs out of Darwin Harbour.
Darwin is on the front line of the crocodile invasion.
And keeping its waters safe is a never-ending task.
As soon as one crocodile is removed, another quickly takes its place.
Yeah, terrified.
I'm terrified of crocodiles.
I wouldn't swim in Darwin Harbour.
Not if you paid me.
