A FISHERMAN has risked his life for what he considered a good cause - booze.

He won two cases of bourbon for jumping on to a log racing down a flooded, crocodile-infested river - in the nude, The Northern Territory News reports.

The tiler, who didn't want to be named, rode the makeshift raft for about three minutes before clambering back into a boat.

"I'd enjoyed a few beers and it seemed a good idea at the time," he said.

Witness Billy Innes said his mate thought nothing of the dangers of drowning or being eaten by a saltwater crocodile, which inhabit the river in large numbers.

"It was hilarious," he said.

The daredevil was camping at the Daly River on Sunday when he accepted the bet.

"Huge trees were hammering down the river," Mr Innes said.

"It was quite a sight. Someone dared him to get on to one of the logs and row across the river."

Keith Parry, 20, was killed while swimming across the Daly River in April 2009. He was crossing the river because he wanted more beer.
