Immigration Minister Peter Dutton must immediately clarify the status of medical care available to people seeking asylum on Manus Island.

"We are hearing that there are no doctors working today in the detention centres on PNG due to International Health and Medical Service failing to properly register its medical practitioners with the Papua New Guinean government," Greens Immigration spokesperson Senator Nick McKim said.

"If this is true, Mr Dutton must take urgent action to ensure proper medical care is available to people who remain Australia's responsibility." 

The government's improper management of Australian Border Force's statutory powers is squarely the fault of Immigration Minister Peter Dutton.

"This government has grabbed for itself a massive range of new powers in its process of militarising the Department of Immigration and Border Protection," Greens Immigration spokesperson Senator Nick McKim said.

"The failure of the Department to ensure that these powers are being used legally falls squarely on the shoulders of the incompetent Peter Dutton." 

The government's confusion over the US refugee “deal" is creating further anxiety and uncertainty for people who have already suffered for far too long, Greens Immigration spokesperson Nick McKim says.

"While the government argues with itself over whether or not this is a people swap, there are men, women and children suffering in Australia's inhumane detention centres due to the ongoing uncertainty," Senator McKim said.

"This 'deal' was apparently signed more than three months ago, yet not a single person has been resettled in the United States."

The Labor and Liberal Parties have voted down a Greens motion which opposed the forced deportations of people seeking asylum on Manus Island.

"Labor and Coalition Senators have today washed their collective hands of responsibility for people seeking asylum who have not had their applications for refugee status assessed in line with the Refugee Convention," Greens Immigration spokesperson Senator Nick McKim said.

"This was a motion supporting basic human rights for those who have already suffered too greatly at Australia’s hands."

The Greens will stand against the government's discriminatory anti-immigration agenda, and specifically against Minister Dutton's power grab through the Visa Revalidation Bill.

"This government has made it clear that they want to see an end to multicultural Australia," Greens Immigration spokesperson Nick McKim said.

"Peter Dutton, our anti-immigration minister, is seeking a further expansion of his powers so he can create two classes of Australian citizens, and undermine the security of all migrants living in Australia."

The Australian government must urgently intervene to halt the forced deportation of Australia's detainees on Manus Island.

"Under the cover of darkness, at least one person seeking asylum has been forcibly removed from Manus Island," Greens Immigration spokesperson Senator Nick McKim said.

"With the illegal detention centre being forced to close and the uncertainty around the US 'deal', this seems to be Peter Dutton's only 'solution' to the humanitarian crisis he has overseen."

The Government has been ordered by the Senate to produce the details of its agreement with the United States to consider resettling some people Australia has detained on Manus Island and Nauru.

"The government has kept this agreement hidden from view, creating unnecessary uncertainty and anxiety for people who have already suffered far too much," Greens Immigration spokesperson Senator Nick McKim said. 

"But from what is on the public record, it is clear that it doesn’t oblige the United States to accept a single person."

The Greens will move to amend Australia's visa laws to give Parliament the power to block foreign leaders from visiting Australia on the grounds of character.

"Parliament is sovereign in this country," Greens Immigration spokesperson Senator Nick McKim said

"Consistent with our position that Parliament should have the final say on Australia going to war, we believe that Parliament should have the right to refuse entry to, or deport, foreign leaders on the basis of their character."

"This issue has been crystallised for us by Donald Trump becoming US President."

The Greens welcome the united front from the long list of community groups and organisations calling for immediate action on offshore detention.

"The situation on Manus Island and Nauru is completely untenable," Australian Greens immigration spokesperson Senator Nick McKim said.

"Resettlement for any refugees in the US now looks extremely unlikely and Prime Minister Turnbull needs to immediately close the camps and bring every man, woman and child in offshore detention here to Australia."

Malcolm Turnbull should scrap his refugee "deal" with the US and bring people detained on Manus Island and Nauru to Australia , Greens Immigration spokesperson Nick McKim says.

"It is becoming increasingly clear that Mr Turnbull is placing his faith in a xenophobic and anti-immigration US President who has a track record of dishonesty and lies," Senator McKim said.

"Only a fool would take Trump at his word."
