A Darwin diver has been commended for his bravery fending off a crocodile that attacked his colleague in waters off the Top End two years ago.
Rupa Manimua was diving for trepang at Knocker Bay, about 180 kilometres north-east of Darwin, when another diver was attacked by a two-to-three metre long crocodile.
The 45-year-old victim was bitten on the head, shoulders, neck and arms.
Mr Manimua managed to pull the victim to the surface but the crocodile's jaws remained locked on.
He then used a screwdriver to fight the crocodile off the victim.
The croc let go and Mr Manimua was able to drag his injured colleague onto a nearby boat, saving his life.
Mr Manimua has today been honoured with a commendation for brave conduct, the fourth highest Australian bravery decoration.
