The Australian Greens have today urged the Gillard government to follow the recommendations of Amnesty International's report to impose time limits on detention and shut down remote detention centres.

"If we want to stop already fragile people from harming themselves or taking their lives, the only way to do it is by closing detention centres on Christmas Island and elsewhere," Greens' immigration spokesperson, Sen. Sarah Hanson-Young.

The Australian Greens are the only political party trying to change unjust laws which are keeping Indonesian children and adults stuck in prison without charge for longer than people accused of serious offences.

"While the old parties squabble about leadership challenges, the Greens are drafting bills and having them referred to inquiries to address the legal and procedural black holes," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said today.

The Daily Telegraph has blown an opportunity to tell its readers the reality of what happens when asylum seekers are released into the community, the Australian Greens said today.

"Last year the paper showed the dangers asylum seekers faced under the Malaysian solution, but this year it has given a false picture of community release programs here on shore," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

"That's a real disappointment because there are so many myths about asylum seekers which continue to be perpetuated.

The UNHCR chief, Antonio Guterres, has last night highlighted the relatively small number of asylum seekers seeking Australia's protection compared to countries including Italy, the Australian Greens said.

"Last year 58,000 people arrived in Italy and Malta and 100,000 reached Yemen, compared to around 6,000 in Australia," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

"Despite what some may want to believe, we do not have a national security problem, we have a humanitarian one and we need to keep things in perspective.

The Immigration Department's figures showing 528 children are being held in immigration detention across the country, giving 528 reasons why the rules need to be changed so children are not simply incarcerated as a matter of course the Greens said today.

The $1 billion Australian taxpayers are spending on private company Serco's detention centre contract would be better off going toward a public denticare scheme, the Australian Greens said today.

"Letting detainees live in the community after initial health and security checks while their protection claims are assessed is 90 percent cheaper and 100 percent fairer compared to a detention centre," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

Sarah's Senate courtyard door stop on the $1billion going to Serco to maintain detention centres compared to having detainees living in the community.

The Greens have today introduced into the Senate a bill to amend the Migration Act to restore judicial discretion to the courts in deciding sentences for convicted people smugglers.

"The Greens have tabled this bill because the government's much-hyped mantra of being tough on people smugglers is not working and is instead leading to injustice," Greens' immigration spokesperson, Sen. Sarah Hanson-Young, said.

"While people smuggling must be tackled, the government continues to punish only the little fish and never the kingpins that actually control the syndicates.
