that Scott Parkin may have been deported to test the Australian public's reaction to anti-terror laws being introduced around the same time as the deportation, a claim that has been denied by Australian Attorney-General Philip Ruddock. On October 31, 2005, Director-General of Security Paul O'Sullivan gave evidence before a Senate Estimates Committee that Parkin was not involved in any violent activity in Australia. O'Sullivan also told the Committee that the adverse security assessment was related to Parkin's "behaviour subsequent to his arrival in Australia". On 6 December 2005, the Attorney-General released the public version of a classified report by the Inspector-General of Intelligence and Security, Ian Carnell, detailing his investigation into the circumstances of Parkin's deportation.

On May 22, 2007, Parkin's supporters released a report, Where the bloody hell are you?, which included 26 statutory declarations detailing Parkin's political activities in Australia prior to the adverse security assessment. On the same day, legal counsel for ASIO head Paul O'Sullivan told the Federal Court that ASIO did not rely solely on information relating to Parkin's activities in Australia. The following day, O'Sullivan refused to answer questions before a Senate committee about the accuracy of his previous evidence that Parkin's security assessment was related to his activities in Australia.
