The Australian based Refugee Action Coalition says a Sudanese refugee who died in an Australian hospital should never have been kept at the Manus Island detention centre in the first place.
Faysal Ishak Ahmed was evacuated to Australia from Manus last week after collapsing at the Australian run detention camp in Papua New Guinea but died on Christmas Eve.
Spokesperson for the Coalition Ian Rintoul said Faysal's poor health was repeatedly brought to the attention of the IHMS medical team on Manus Island through letters and complaints but these were ignored.
He said Faysal should have received treatment offshore much sooner.
"He's just been fobbed off, the response has been 'thanks for the complaint, it has been received, you'll get a written report within a week', those reports never eventuated," said Mr Rintoul.
"One response says 'an appointment has been made with an ear, nose, and throat specialist', but they've got no idea when a specialist is going to be on Manus Island, 'they'll let them know', it is a litany of dismissal."
Mr Rintoul said the last few times Faysal approached IHMS he was seen by a nurse and not a doctor.
The PNG Supreme Court ruled in April that the centre is illegal and must be shutdown but no timeline has been given by the Australian or PNG governments for its closure.
