Liberals promise to close Inverbrackie detention centre in the Adelaide Hills Security staff at the Inverbrackie detention centre. Picture: Michael Marschall Source: adelaidenow THE Federal Coalition will close down the Inverbrackie detention centre in the Adelaide Hills if it wins the September Federal Election. Opposition immigration spokesman Scott Morrison said policies to deter asylum seekers on boats would mean Inverbrackie, at Woodside, was no longer needed and it would be shut "as soon as practicable." "If elected later this year the Coalition could be faced with a backlog of more than 20,000 people in various forms of detention as well as in the community on bridging visas - this compares to just four people when the Coalition left office," Mr Morrison said. This will be a debilitating legacy to work through, courtesy of Labor's failures. As we work through Labor's mess, it will be a priority for the Department of Immigration to decommission Inverbrackie. Member for Mayo Jamie Briggs said it was recently discovered Inverbrackie was housing an Egyptian being sought by Interpol as a terrorism suspect. "The Inverbrackie facility was arrogantly imposed on the local community without consultation by the Gillard Government," Mr Briggs said. It has also broken yet another promise: that only low-risk detainees would be sent there. The Inverbrackie Alternative Place of Detention is on Defence Department property . It contains 80 former defence personnel houses and accepted its first immigration detainees on December 18, 2010. It houses up to 400 people who are considered suitable for a low-security facility, and the Government says it will not be expanded. Opposition Leader Tony Abbott, speaking during this weekend's visit to Adelaide, said the Coalition "will be in the business of restoring our borders and closing our on-shore detention centres" but did not elaborate on what would happen to those asylum seekers now in detention at Inverbrackie. "If you stop the boats you can start to close down detention centres on the mainland, starting with centres like Inverbrackie," Mr Abbott said. At a Liberal Party rally at Nazareth Catholic College in Flinders Park yesterday, he also vowed a Coalition government would create economic conditions to help the stalled expansion of the Olympic Dam mine proceed. The Opposition Leader blamed the state and federal governments for it being put on hold by BHP Billiton. He said he could not guarantee the project would proceed under the Coalition but added: "I can promise there will be no obstacles from government that will impede its progress." He also reiterated the party's $500 million commitment for the Darlington roadway interchange - revealed in The Advertiser yesterday - as the first step in plans for a north-south expressway system. He said the commitment would go to Infrastructure Australia for a cost-benefit analysis. Mr Abbot said the project was expected to require state funds of up to $500 million to complete. However, State Mineral Resources Minister Tom Koutsantonis accused Mr Abbott of "over-spruiking" by suggesting the Coalition could get Olympic Dam expanded, saying Mr Abbott would have to change international conditions. Mr Koutsantonis said: "What will get Olympic Dam over the line is not conditions in Australia or South Australia." It is the price of copper and uranium and the development of new technology to reach one of the most difficult ore bodies in the world.
