Tony Abbott and Bill Shorten's comments, suggesting that Europe should follow Australia's lead on towing refugees back to danger, are embarrassing and have disgraced Australia on the international stage, the Australian Greens have said.

"It is shameful that, while the rest of the world is doing all it can to help Syrian people who are searching for safety, Tony Abbott and Bill Shorten want to see them towed back to danger," the Greens' immigration spokesperson, Senator Sarah Hanson-Young said.

Following New Zealand's decision to suspend all justice funding being given to Nauru, the Australian Greens have called on the Abbott government to do the same.

"As long as the Abbott government keeps sending cash to Nauru, Australian tax payers' money is being wasted," the Greens' immigration spokesperson, Senator Sarah Hanson-Young said.

"Gripped in the throes of a systemic legal collapse, the Nauruan government should not be receiving kickbacks from Australia.

Children are being assaulted, women are unsafe and the detention camp on Nauru cannot be allowed to continue in its current form, a Senate Inquiry report has said today.

"It can't be made any clearer that locking children up with the guards on Nauru is exposing them to abuse," the Greens' immigration spokesperson, Senator Sarah Hanson-Young said.

"The government's head-in-the-sand approach to mounting evidence of systemic child abuse is causing immeasurable harm.

The Cambodian refugee deal has always been an expensive and cruel sham, the Australian Greens have said.

"The Cambodia deal has been a spectacular, 55 million dollar failure from the Abbott government," The Greens' immigration spokesperson, Senator Sarah Hanson-Young said.

"Dealing in cruelty with a corrupt regime is a costly business and, in this case, the Abbott government has simply been duped.

 HESTA owned a 3 per cent stake in Transfield, valued in excess of $18 million. 

“We welcome HESTA’s corporate leadership on this issue and congratulate HESTA CEO Debby Blakey for taking this step,” Greens Spokesperson for Immigration Senator Sarah Hanson-Young said today.

Media reports have revealed the Abbott Government is planning to sign new five to seven year contracts to keep Manus Island and Nauru detention camps open, costing billions in taxpayers dollars and continuing Australia’s cruel offshore detention program.

"These offshore hellholes are costing taxpayers billions, and now the Government wants to give even more money to the companies who make big profits from locking up children," Greens Immigration Spokesperson Senator Sarah Hanson-Young said.

The Greens have called on the Australian Government to explain why they have proposed to allow fast-tracking of refugee visa applications for a cost of $19,000 when there are already refugees waiting for decades to have their claims processed.

The Greens have expressed serious concerns over growing tension between Papua New Guinean authorities and the Australian Department of Immigration and Border Protection, calling on the Australian Government to explain what has happened with three Australian Wilson guards from Manus Island accused of raping a local PNG woman.

The Greens have expressed concern over allegations of violence including murder and rape on Manus Island involving detention centre staff and have called on the Australian Government to give a full explanation of what has occurred.
