The Australian Greens have condemned Kevin Rudd's latest cruel manoeuvring and bribery of Nauru.

Australian Greens Leader Senator Christine Milne said: "The Prime Minister is caught out by his own rush to cruelty.

"Kevin Rudd said there would be no exceptions, but when it became clear he couldn't send children under seven or pregnant women because of malaria, he had to hurriedly cobble together a new cruel punishment for them.

"Kevin Rudd has come up with Nauru not only as a place of punishment, but as a place of resettlement. It is cruel and absurd.

The Australian Greens have launched a new plan to give refugees a safer pathway to protection.

The plan includes increasing the government's humanitarian intake to 30,000 a year, providing an extra $70 million per annum in emergency funding to help fast track the processing of refugee claims in Indonesia and shutting down all detention camps in Nauru and Papua New Guinea.

The Greens’ approach to refugees will save lives by offering a safe, legal and humane alternative to dangerous boats – instead of the major parties’ escalating arms race of cruel deterrence measures.

Kevin Rudd’s decision to dump every refugee in Papua New Guinea, one of the world’s most impoverished countries, is shameful. It is no wonder Tony Abbott has welcomed it.

Not to be outdone by Labor, the Coalition has adopted Labor’s indefinite offshore dumping policy and also promised to open up a detention camp for refugees in a slum in Nauru.

Prime Minister Rudd's refugee announcement is Australia's day of refugee shame, Greens Leader Senator Christine Milne said.

"A rich country like Australia paying off a poor country to take our desperate refugees is passing the buck and an abrogation of our responsibilities to people and the international community," Senator Milne said.

"It's not a regional solution, but a radical, right-wing, hard-line response. Manus Island will be Australia's gulag in PNG.

The Greens, Amnesty International, the Anglican Church, Refugee Rights Action Network and many others have joined together to host the Refugee Welcome Fiesta in Fremantle tomorrow.

The all-inclusive community event marks the end of World Refugee Week and also commemorates Welcome To Australia's national Walk Together.

Senator for Western Australia Scott Ludlam said "the dangerous trend of politicians exploiting refugees for political advantage is toxic for all immigrants, and indeed toxic for all Australians. We are gathering to take a stand for tolerance and humanity".

The arrival of refugees in Geraldton, WA, is a clear sign that the government’s harsh treatment of refugees isn’t stopping people from coming by boat or making them safer. The Australian Greens are calling for an urgent boost in the number of refugees being resettled in Australia.

“The government’s policy of cruelty has entirely failed,” the Greens’ immigration spokesperson, Senator Sarah Hanson-Young said.

“Offering a secure path to safety means refugees won’t be forced to take dangerous boat journeys.

Criticism of the Manus Island detention centre from a member of the government’s own expert panel on asylum seekers shows that Labor’s unravelling Pacific Solution needs to be shut down immediately and children and families need to be brought to the mainland.

“Labor’s policy of offshore detention is hanging in tatters and it’s clear that these island prisons need to be shut down,” the Greens immigration spokesperson, Senator Sarah Hanson-Young said.

“Children do not belong in detention.
