Senator CASH (Western Australia) (14:30): Mr President, I ask a supplementary question. I refer the minister to the comments made by an immigration spokesman regarding the reasons for the contract blow-out: 'It is being driven by a simple reason, the expansion in the number of centres in the network.' Given that the number of detention centres has increased to 20 under the Labor government, will the government finally admit that it has lost control of Australia's borders and that this cost blow-out that Australian taxpayers are paying for is a problem entirely of this government's own making?
