Senator RUSTON (South Australia—Minister for Families and Social Services and Manager of Government Business in the Senate) (14:56): I thank Senator Wong for her question. I've had the opportunity since yesterday to consider the question that was asked of me by Senator Gallacher. I reject the premise of the question, because at no time has there been a finding that the income compliance program was not valid. Senator Wong: They're your words! You said 'not valid'! The PRESIDENT: Order! Senator Wong, you've got the opportunity— Senator RUSTON: Senator Wong, you are wrong. The PRESIDENT: Senator Wong, you've got an opportunity to ask a supplementary question. I believe the minister has concluded her answer. Senator Wong.
