arrivals seeking asylum in Australia has been of major significance throughout the tenure of the Gillard government. During the first Rudd-Gillard leadership spill of 2010, outgoing Prime Minister Kevin Rudd said he feared a "lurch to the right" under a Gillard prime ministership. Rudd had dismantled key components of the Howard government's asylum seeker policy, including the Pacific Solution offshore processing system. The Gillard government initially maintained Rudd's policies, downplayed the notion of "pull-factors" attracting increased numbers of boat arrivals and criticised offshore processing at Nauru but, by September 2012, after the High Court had rejected an alternative plan to exchange asylum seekers for processed refugees from Malaysia amid an extended surge in boat arrivals and deaths at sea, the Gillard government confirmed support for offshore processing, and announced it would re-open sites at Nauru and Manus Island. After winning leadership of the Labor Party, Gillard identified addressing the issue of unauthorised arrivals of asylum seekers as one of three key policy areas requiring the attention of her government. She announced that negotiations were underway for a return to "offshore processing" of asylum seeker claims. Gillard ruled out a return to processing at Nauru because it was not a signatory to the UN Refugee Convention, and named East Timor as a preferred location for new detention and processing facilities. The East Timorese government rejected the plan. For the final few years of the Howard government, people smuggling between Indonesia and Australia had virtually ceased and Australia's offshore detention centres were near empty. The newly elected Rudd government announced a series of measures aimed at achieving what it described as a more "compassionate policy". The Pacific Solution had involved offshore processing, a system of "temporary protection visas" for unauthorised arrivals, and a policy of turning back boats where possible. The Rudd government dismantled all three components, dubbing them "ineffectual and wasteful". Throughout 2009–2010, a flow of boat arrivals re-emerged. In October 2010, the Gillard government announced that it would open two detention centres for 2000 immigrants, due to the pressures in allowing women and children to be released into the community. One to be opened in Inverbrackie, South Australia and one in Northam, Western Australia. She said it would be a short-term solution to the problem and that temporary detention centres will be closed.
