A convicted killer who bragged to a fellow inmate about eating his victim's penis has died from a 'very aggressive' cancer.

David Kevin Loader, 59, was serving a life sentence for the 2001 killing of George Martin, 64, when he died from metastatic cancer earlier this year. 

A coronial inquest in Darwin on Tuesday heard Loader was diagnosed in November last year. 

Loader was transferred to the Royal Darwin Hospital, where he took his final breath on January 11.

Loader's treatment and care in custody was 'appropriate and of a high standard,' Coroner Greg Cavanagh found.  

'When people are in the care of the state, that care needs to be examined from time to time and the reasons are obvious,' he said, the NT News reported.

'They've got no other rights when they're in custody, their rights to complain, move, shift, (say) 'I don't like it here' - they haven't got any of those rights at all.' 

Loader was serving a life sentence, with a 20-year non-parole period, for killing Mr Martin at a campsite at Mandorah, near Darwin, on July 5, 2001.

The Northern Territory Supreme Court heard in 2002 the pair had been drinking heavily before Loader 'blanked out' and woke to find Mr Martin laying face up in a large fire near his camp.

Loader was arrested five days later at Mount Isa in Queensland after police searched the campsite and found human bones in the fire pit. 

Inmate Daymon Hannila told the court during the trial he thought Loader was joking when he described how he killed Mr Martin.

'(He said) that he hit the person on the head with a rock, cut off his leg, put it in the fire and cooked it,' Hannila said via video link from Townsville prison.

He told the court how Loader claimed to have cut the man's penis off, cooked it in the fire and ate it. 

Hannila said Loader told him it tasted like chicken.
