The Australian Greens want Prime Minister Tony Abbott to join President Barack Obama and others around the world in condemning new laws in Uganda that outlaw homosexuality with sentences of life imprisonment.

"Tony Abbott has a moral obligation to condemn these horrific laws and to work with the global community to guarantee the safety of all those named as LGBTI in the Ugandan tabloid Red Pepper," Greens Leader Christine Milne said.

The Australian Greens have called for Scott Morrison to be sacked from the Ministry following revelations that the violent attacks on Manus Island took place inside the refugee prison camp, resulting in the death of asylum seeker Reza Berati.

"The Prime Minister must sack the Minister and close his cruel refugee prisons immediately," Greens Leader Christine Milne said.

"Tony Abbott must take personal responsibility for the failure of the morally bankrupt and cruel offshore processing regime that was started by Labor and embraced by his government.

The Abbott Government's asylum seeker policy is cruel and inhumane. The Australian Greens are calling for the Manus Island Detention Centre to be shut down immediately.

The Australian Greens have called on Tony Abbott to initiate a Royal Commission into the conditions and management of Australia's offshore detention camps, which led to the death of an Iranian refugee while in Australia's care on Manus Island.

"The tragedy of a refugee killed while in Australia's care should be the final nail in the coffin for Labor and the Abbott government's morally bankrupt and cruel offshore processing regime," Australian Greens Leader, Senator Christine Milne said.

Australians Greens Leader Christine Milne says the Abbott government must immediately confirm or deny claims that asylum seekers are being told they must return home or face indefinite detention.

"Under international law it is illegal for a country to send a refugee back to the country they escaped from. It is illegal and cruel," Senator Milne said.

"It is a shameful and cruel government that gives desperate asylum seekers a Sophie's choice between indefinite detention and return to the violence they have fled.

Australian Greens Leader Christine Milne has called for Immigration Minister Scott Morrison to immediately explain the extent of the Australian Government's involvement with security forces implicated in violent interactions on Manus Island.

"This is the second time PNG security forces have been implicated in violence. Scott Morrison must immediately explain whether they are on our pay roll and the exact extent of their involvement with Australian operations at Manus Island," Senator Milne said.

News today that Immigration Minister Scott Morrison has directed department officials and detention centre staff to refer to asylum seekers as 'illegal' is not only discriminatory but a disturbing move to politicize public servants.

"People seeking asylum - by boat or any other way - are not illegal, they are human beings," said Australian Greens Leader Senator Christine Milne.

"It is not illegal to seek asylum under Australian or international law.

"Dehumanising people is never acceptable.

The Australian Greens say Labor Senator Lin Thorp's claims that her party's asylum policy was not set in stone shows Labor will say and do anything to win.

Tony Burke reiterated today that children will be sent to Nauru and no one should believe otherwise, but Senator Thorpe, with an eye to the much more caring Tasmanian community, says the policy is not set in stone.
