The Australian Government cannot just wash its hands of the people it exiled to Papua New Guinea, the Greens say.

“Today is a day to remember the people who died as a result of being illegally exiled to Papua New Guinea, and the countless other lives that were destroyed,” Greens Immigration spokesperson Senator Nick McKim said.

“People who sought asylum in Australia remain Australia’s responsibility under international law, and no amount of bureaucratic maneuvering can change that fact.

Labor’s refusal to even discuss a more humane approach to refugees shows the party leadership has learned nothing from five years of death and misery on Manus Island and Nauru, Greens Immigration spokesperson Nick McKim says.

“Bill Shorten and the factional bosses have decided yet again to lock in behind Peter Dutton’s campaign of misery,” Senator McKim said.

“This is a crackdown on compassion and hugely disappointing to the millions of Australians who don’t support what is being done in their names.”

Today’s withdrawal of International Health and Medical Services (IHMS) as the Australian government’s health provider on Manus Island will mean further erosion of crucial health support for refugees and people seeking asylum in Papua New Guinea, Greens Immigration spokesperson Nick McKim said.

"Health supports for detainees on Manus island have never been at an acceptable level, but it now seems inevitable that the humanitarian catastrophe will worsen with increased risk of further self-harm and mental illness," Senator McKim said.

The federal government's neglect of refugees and people seeking asylum on Manus Island has led to a re-escalation of tension and danger, Greens Immigration Spokesperson Nick McKim says.

"For the last few days access to two facilities where more than 250 refugees and people seeking asylum are living has been blocked by the landowners who are in dispute with the PNG Immigration department and contractors," Senator McKim said.

Immigration Minister Peter Dutton has again escalated the Manus Island humanitarian emergency by ordering the use of force against innocent people.

"Dutton tried to starve and dehydrate the men out of his prison, now he's using violence to try to force them out," Greens Immigration Spokesperson Senator Nick McKim said.

"What is happening on Manus Island is an blatant abuse of people's rights by a minister who has abandoned all sense of human decency."

Threats of using force against detainees at the Manus Island detention centre are unprecedented and potentially highly dangerous, Greens Immigration spokesperson Nick McKim says.

“The instructions for this threat have no doubt come directly from Dutton’s office,” Senator McKim, who is in Papua New Guinea, said.

“These men are Australia’s responsibility and remain so. They are in Maclolm Turnbull’s care as he proved when he knocked back New Zealand’s offer to resettle some of the men.”

Peter Dutton has no choice but to immediately end the humanitarian crisis he has created on Manus Island, Greens Immigration Spokesperson Nick McKim says.

“There are hundreds of men in Dutton’s care who are suffering greatly because of his decisions,” Senator McKim, who is in Papua New Guinea, said.

“They have had their basic rights removed and have been placed in an impossible situation with danger everywhere they turn.”

“Dutton must evacuate these men to safety and restore the basic necessities of life to them.”

Peter Dutton must intervene to end the humanitarian crisis he has created on Manus Island, Greens Immigration spokesperson Nick McKim says.

"Peter Dutton must not go ahead with his plan to cut off water, food and electricity to force people out of his Manus Island prison," said Senator McKim, who is currently on Manus Island.

"This situation could become violent because of his creation and escalation of this humanitarian crisis."

"There is nowhere safe in Papua New Guinea for these men to go – they must be evacuated to Australia."

Peter Dutton trying to move his Manus Island prisoners to Nauru is a cruel and unfair move which reeks of panic and desperation, Greens Immigration spokesperson Nick McKim says.

“The men on Manus Island have suffered long enough, yet Dutton wants to take them out of one frying pan and straight into another one,” Senator McKim said.

“Amnesty International says the conditions in Dutton’s Nauru prison amount to torture – it is clearly not a suitable place for people seeking asylum.”
