Inside the Rugged Lives of Crocodile Hunters

A photographer explores the complex issues around crocodile conservation and hunting in Australia.

“It’s insanely dangerous,” says Trevor Frost, a photographer and National Geographic grantee. “It’s hard to focus on taking pictures and at the same time make sure that your hands and arms aren’t going to get bitten off.”

Frost has spent the last three years documenting saltwater crocodile hunting in northern Australia, where the gigantic animals have made a comeback from near-extinction in 1971 to as many as 100,000 today in the Northern Territory alone.

Crocodiles numbers have bounced back so much that some people started worrying about their safety, and called for widespread culls of the animals.

To ease concern, the Northern Territory decided to allow a limited number to be hunted each year. The hunt gives people a way to make money from the crocodiles, creating an incentive to keep them around. The tanned skin of a 14-footer can be worth up to $10,000, Frost says. And a skull can sell for as much as $3,000.

This concept, sometimes referred to as “if it pays, it stays” conservation, has been tried around the world in many other contexts. In a lot of cases, it fails—resulting in poaching of the protected animal. But Frost’s years of on-the-ground reporting have convinced him that in Australia, when it comes to saltwater crocodiles at least, the approach works.

The hunter must have a permit to kill a crocodile, and it specifies what size he’s allowed to take. He must film the catch and slaughter and present the video to the authorities, Frost says, so that they can verify it was killed according to humane standards.

He tells the story of one the most momentous—and emotional—hunts he went on. An aboriginal landowner whose wife was nearly attacked by a giant crocodile on their land called in two hunters that Frost had been shadowing. The hunters and Frost set out at night in a 14-foot aluminum boat, looking for the croc. One person manned the motor; the other stood on the bow swinging a spotlight back and forth looking for the crocodile’s eye shine.

They found him. Based on the distance between the eyes, they knew he was massive. Keeping the light in the croc’s eyes so it couldn’t see, the hunters pulled the boat up close. They shot a harpoon into the back of its neck. Then the fight began.

Gunther Trnka, a real estate agent in Darwin, Australia, keeps a 12 foot male saltwater crocodile named Jaws in his backyard.

“The harpooner takes hold of the reel and plays it out like a fish,” Frost says. “It’s very much a dance.”

This massive croc was so strong that it ran all the slack out of the reel and began pulling the boat. “We were being dragged pretty quickly,” Frost says. After two hours, it finally started to tire. It would come to the surface, hiss, and then dip back under.

Finally, the boat was able to get close enough to lasso its jaws, which would need to be duct-taped shut before the hunters could shoot it dead.

All of a sudden, the crocodile bit the side of the boat and began thrashing. The boat was in danger of tipping over. One hunter yelled at them to sit down. “I got two cameras around my neck and I just drop to the bottom of the boat,” Frost says.

Eventually, the croc tired. They were able to lasso it. Using a revolver, one of the hunters shot it in the brain stem, causing immediate death. It was 2 a.m. when they got back to shore.

When they measured the crocodile, it came in at nearly 16 feet long.

Frost didn’t grow up around guns or hunting and doesn’t consider himself a hunter. I asked him if it was hard watching an animal fight so hard for its life and ultimately lose.

“It’s definitely emotional. More emotional than anything was that it was an 80-year-old animal,” he says. “It was as old as my grandmother. It had been through the second World War, probably the Great Depression. It had seen so much.”
