When Marvin Muller began snapping pictures of the epic animal battle at Lake Moondarra near Mount Isa, he never expected they would go viral.

"We were just in awe and just trying to get some nice photos," he said.

Five months on and that Saturday at the lake has earned Mr Muller more money than some people make in a year.

"I just calculated all the monthly summaries, and we're sitting on about $26,900 at the moment," he said.

"It's pretty awesome, I never would have thought we'd make that much out of it. Every bit of money is nice to get in," he said.

Mr Muller employed a company to syndicate the pictures to international media organisations, which means whenever the pictures are used abroad, Mr Muller should be paid a fee.

"We've been getting money in from all over the world, from Lithuania to Mexico to South America," he said.

Mr Muller says while not every international media organisation has paid to use the images, he does not intend to battle for the money because it's a complicated process.

The income from the pictures has helped pay off his car loan and fund an upcoming holiday to Tonga, where he plans to swim with humpback whales.

As for why the pictures proved so popular, Mr Muller says there were two main factors working in his favour.

"There are other photos of snakes eating animals out there, but it's in Australia so that adds to it for everyone from overseas," he said.

"The other thing is it was a slow news day, which was lucky for us."
