An extensive search for a missing man in croc-infested waters has been called off, after police found DNA evidence to suggest the man is dead.
On Saturday, three men were out on a boat near Wadeye, about 400km southwest of Darwin in the Northern Territory, when their boat capsized.
Two of the fishermen were able to swim ashore after being in the water for about an hour, however, the third man on the boat, a 28-year-old, did not make it to land.
"After an intensive three-and-a-half-day air, land and sea search that involved police, Parks and Wildlife, NTES volunteers, local rangers and community, the missing man has not been located," Superintendent Kirk Pennuto said on Wednesday.
"The search effort has been exhaustive and has identified evidence, including DNA evidence, that the missing man is no longer alive."
He added there are a "number of possibilities" which will be examined for the Coroner, to determine the cause of death.
Authorities said a large crocodile was removed from the area on Tuesday and that the area is known for its challenging waters which are home to large crocodiles.
"The man's family is being offered welfare and pastoral support. Our thoughts are with them," Supt Pennuto said
The boat rolled over in a channel between the mainland near Old Mission and Dorcherty Island to the north about 7.30pm, AAP reported.
The two men who made it back to shore when the boat capsized were treated at the local clinic for shock and exposure, but were fine otherwise.
All three of the men on the boat were from Wadeye.
