The Refugee Action Coalition in Australia says the death of the Iranian asylum seeker whose life support was turned off on Friday evening is senseless and inexcusable.
24 year-old Hamid Kehazaei was medivacced from the Australian detention on Manus Island in Papua New Guinea to Brisbane last Wednesday suffering from septicaemia caused by an infection that spread from a cut in his foot.
He had a heart attack before being declared brain dead on Tuesday.
The Coalition's Ian Rintoul says the fact that a man could die in this way, while supposedly in the care of the Australian Immigration Department, says everything about the lack of care on Manus Island.
Mr Rintoul says infections, skin disease are endemic in the detention centre.
He says it's absurd for Australia's Immigration Minister Scott Morrison to claim that asylum seekers who get ill on Manus Island get outstanding care.
The refugee advocate says Mr Kehazaei's death speaks of the medical neglect, the culture of punishment and indifference that pervades Manus Island.
He says Hamid Kehazaei, like Reza Barati, are victims of the offshore processing regime being run by the government.
Reza Barati was allegedly beaten to death by a group of guards during a riot in February inside the asylum seeker processing centre on Manus.
Ian Rintoul says all the detainees on Manus must be brought to the mainland.
