The Greens welcome the High Court’s decision regarding the government’s ability to deport First Nations peoples.

“Trying to deport First Nations peoples whose country we stole is a fundamentally racist thing to do,” Greens Immigration and Citizenship spokesperson Senator Nick McKim said.

“All First Nations peoples who are in Immigration detention should now be immediately released.”

“It is also time to rein in the authority of both the Immigration Minister and the Minister for Home Affairs so we don't see these kinds of gross abuses of power.”

The Greens have welcomed the removal of the Border Force Act gag on doctors, but have called for it to be removed from all other detention centre workers and contractors.

"This is a humiliating backdown by the Government and an admission that all departmental workers and contractors were in fact gagged by Section 42 of the Border Force Act," Australian Greens Leader Senator Richard Di Natale said.

"This gives the lie to the government's claim that workers and contractors are protected as whistle-blowers."
