To conserve or cull? Life in Australia's crocodile capital

It's dawn on Darwin Harbour and government ranger Kelly Ewin - whose job is to catch and remove crocodiles - is balancing precariously on a floating trap.

Heavy rain clouds from the storm that has recently ed are overhead. The engine of the boat has been cut so now it's mostly silent – that is, apart from the intermittent splashing coming from inside the trap.

"You get pretty much zero chances with these guys," says Ewin as he attempts to loop a noose around the jaw of the agitated reptile.

We're in Australia's Northern Territory (NT), home to an estimated 100,000 wild saltwater crocodiles, more than anywhere in the world.

The capital, Darwin, is a small coastal city surrounded by beaches and wetlands.

And, as you quickly learn here in the NT, where there is water, there usually are crocs.

Saltwater crocs - or salties, as they are known to locals - were nearly hunted to extinction 50 years ago.

After World War Two, the uncontrolled trade in their skins soared and numbers fell to around 3,000.

But when hunting was banned in 1971, the population started rising again - and fast.

They still are a protected species, but are no longer threatened.

The recovery of the saltwater crocodile has been so dramatic that Australia now faces a different dilemma: managing their numbers to keep people safe and the public onside.

"The worst thing that can happen is when people turn [against crocodiles]," explains croc expert Prof Grahame Webb.

"And then a politician will invariably come along with some knee-jerk reaction [that] they're going to 'solve' the crocodile problem."

The NT's hot temperatures and abundant coastal surroundings create the perfect habitat for cold-blooded crocs, who need warmth to keep their body temperature constant.

There also are big saltie populations in Northern Queensland and Western Australia as well as in parts of South East Asia.

While most species of crocodile are harmless, the saltie is territorial and aggressive.

Fatal incidents are rare in Australia, but they do happen.

Last year, a 12-year-old was taken - the first death from a crocodile in the NT since 2018.

This is busiest time of year for Ewin and his colleagues.

Breeding season has just started, which means salties are on the move.

His team are on the water several times a week, checking the 24 crocodile traps surrounding the city of Darwin.

The area is popular for fishing, as well as for some brave swimmers.

The crocodiles that are removed from the harbour are most often killed, because if they are released elsewhere, they're likely to return to the harbour.

"It's our job to try and keep people as safe as we can," says Ewin, who's been doing his "dream job" for two years. Before that, he was a policeman.

"Obviously, we're not going to capture every crocodile, but the more we take out of the harbour, the less risk there's going to be an encounter with crocodiles and people."

Another tool helping to keep the public safe is education.

The NT government goes into schools with its programme "Be Crocwise" - which teaches people how to behave responsibly around croc habitats.

It's been such a success that Florida and the Philippines are now looking to borrow it, in order to better understand how the world's most dangerous predators can live alongside humans with minimal interactions.

"We're living in crocodile country, so it's about how we [keep ourselves] safe around the waterways - how should we be responding":[]}
