Dr Russel Norman: How can he be confident in the Minister’s oversight of the Government Communications Security Bureau when the inspector-general of Intelligence and Security, in his annual report of 2011, raised concerns about the operation of Government Communications Security Bureau authorisations to intercept communications, and, so far as we are aware, the Minister has never taken any action to follow up with the bureau why the Inspector-General has raised these concerns in his last report and what the Minister has done about it?
