An examination of the remains of two crocodiles killed by wildlife officers has confirmed the death of a Far North Queensland publican who disappeared while fishing on Saturday.
The crocodiles, which measured 4.1 metres and 2.8 metres, were found about 1.5 kilometres from where Kevin Darmody was last seen at Kennedy Bend in the Lakefield (Rinyirru) National Park.
Authorities believe Mr Darmody, 65, had gone to the water's edge to retrieve a fishing lure when he was taken.
Wildlife officers confirmed remains were found inside both of the reptiles, which were examined at the scene.
Department of Environment and Science northern wildlife operations manager Michael Joyce said rangers killed the crocodiles "together … within 10 seconds of one another" on Monday night.
He said it was highly unusual to find two crocodiles feeding on the remains of one human attack victim.
"We didn't believe it was common but this is the second time this has occurred, the last one was during the Hinchinbrook fatality, and it is certainly something we're learning," Mr Joyce said.
"It's obviously something that does occur in crocodile populations as far as behaviour is concerned."
A formal identification process will begin and a report will be prepared for the coroner.
Police Inspector Mark Henderson said it was a "tragic, tragic ending" for Mr Darmody's family and the tight-knit community of Laura, in southern Cape York.
He said the groups fishing at Kennedy Bend on the day were "all locals" who "know the area very well".
"Again, sadly, yet another reminder not to [get complacent] and to heed the signs that are put there for a reason," Inspector Henderson said.
Kennedy Bend is known as a good spot for barramundi near the edge of the main road through Lakefield National Park.
But anglers who fish there regularly say it's notorious for the presence of many crocodiles.
