Senator CONROY (Victoria—Deputy Leader of the Opposition in the Senate) (14:59): My question is to the Minister for Defence. The minister has now had more than a week to find out how a South Australian Liberal party banner was used as a backdrop for a press conference on RAAF Base Edinburgh in Adelaide by the Prime Minister and the South Australian Liberal leader on 13 March—two days before the South Australian election. Minister, who authorised the use of this banner?
