While most laughed off the wild antics, others said the man was lucky to be alive.
"Mate there are way easier ways to off yourself if you have a death wish, just saying," one said.
The photo comes less than a month after an enormous crocodile launched itself into a fishing boat in the Northern Territory, injuring one of the people inside.
Rangers have spent the past month combing the waterways at Kakdu National Park to try and find the crocodile that was behind the April 24 attack.
NT Health said a 32-year-old man from Wollongong in NSW was injured after the crocodile, believed to be around 5m long, flung itself out of the water and into their boat.
"He was fishing on the South Alligator River with three friends in a boat on the night of April 24," a spokesman for the department said.
"A crocodile launched into the boat, attacking his seat and injuring the man."
The group of fishermen had stopped on the river to cook dinner on-board the boat when the shocking attack occurred.
The man was lucky to escape with minor injuries, including a graze to the side of his body.
There have reportedly been six crocodile attacks in Australia this year, the most since 2017.
