The man, known as Ryan, was last month exploring the northern Western Australia coast near Kalumburu in his kayak.
Having been left on the remote Governor Island, the man realised he didn't have enough supplies and attempted to paddle the four kilometres or so back to the mainland.
However, he spotted a six-metre saltwater crocodile and every time he attempted to leave, the creature would make his presence felt, leaving the adventurer stranded for a fortnight.
Mcleod said Ryan was a "very, very lucky man".

"He said every time he got in his little kayak, which was only 2.5m long, this crocodile - who has lived there for many years and is a monster - chased him," Mcleod said.
"He said he was there for a fortnight and he came to the conclusion very quickly that he couldn't get off there without attracting this crocodile," Mcleod told the ABC.
Mcleod said he has spotted the crocodile in question a few times in the region.
