Refugee advocates are accusing authorities in Papua New Guinea and Australia of a conspiracy to cover-up an investigation into the death of an Iranian asylum seeker at the Manus Island detention centre in February.
The company that ran the centre when violent clashes occurred, G4S, has refused to cooperate with the investigation, and the Australian Federal Police have declined a request to help PNG police.
The AFP, who currently have about 70 officers in PNG, says it refused because it has no operational jurisdiction there.
But the spokesperson for the Australia-based Refugee Action Coalition, Ian Rintoul, says there's more to it.
"I think we've got authorities in Papua New Guinea and Australia who have got no interest whatsoever in getting to the bottom of who killed Reza Berati and who is responsible for the attack on 80-odd others on Manus Island."
