Australians will attend rallies across the country today and tomorrow for World Refugee Day (officially June 20) in support of a fairer go for refugees.

"The Australian Greens are working to put time limits on detention into legislation, because we know the current system is causing easily preventable mental and physical damage to already fragile people," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

The Australian Government must urgently move 18 Indonesians who claim they are minors out of adult prisons and into appropriate facilities while their cases are being reviewed, the Australian Greens said today.

"If you think they might be children, get on with it and get them out of adult prisons now and into facilities appropriate for children," Greens' immigration and youth affairs spokesperson, Sen. Sarah Hanson-Young, said.

Desperate people will keep risking everything they have and flee for Australia via leaky boats if they feel they have no other alternative because of limited protection options, the Australian Greens said today.

"In the rush to punish people smugglers, we mustn't lose sight of the bigger picture and the causes that force people to run for their lives," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

Independent Rob Oakeshott MP is continuing to do the Gillard government's bidding on reviving offshore processing today with his Malaysia bill, the Australian Greens said.

"Mr Oakeshott is still doing the government's dirty work to breathe life into a policy which the High Court ruled last year was illegal and would strip current protections away from refugees," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

The Australian Greens have today called on the government remove all young Indonesians from adult facilities until the review is completed or their correct ages are determined.

"The risk of further damage to at least 22 children whose cases are being reviewed is far too great," Greens' immigration and youth affairs spokesperson, Sen. Sarah Hanson-Young, said.

"The revelations by Fairfax that another boy has been prosecuted and convicted as an adult is but the latest example in this international scandal involving Australia's treatment of Indonesian children

Amnesty International's latest annual report card explains in clear terms the risks involved were the Gillard government to succeed in its quest to resurrect the inhumane Malaysian people swap, the Australian Greens said today.

"The report states the deal to expel 800 asylum seekers to Malaysia in exchange for 4,000 refugees who were awaiting resettlement would contravene our international obligations to people seeking our protection," Greens' human rights spokesperson, Sen. Sarah Hanson-Young, said.

The Australian Greens have backed a High Court challenge to the indefinite detention of refugees who have been issued with adverse security assessments by ASIO, a move the party says supports the Greens announcement this week to amend the ASIO act to allow for appeal rights and review mechanisms for refugees and asylum seekers.

Sarah gave comment in Canberra today on Schapelle Corby's sentence reduction and the treatment of Indonesian boat crew.

A new psychological condition diagnosed among asylum seekers held in indefinite detention is further evidence of the need to put time-limits on detention and close remote and isolated detention centres, the Australian Greens said today.

"The discovery of this new mental illness syndrome is nothing for Australia to be proud of," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

The Australian Greens said today they will seek to amend the ASIO Act so refugees, including children, are no longer detained for the rest of their lives because of adverse security assessments which cannot be challenged.

"There is a problem with the current law that allows for a young mother and her children to be detained indefinitely, effectively for the rest of their lives without explanation or ability to challenge," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.
