Senator CONROY (Victoria—Deputy Leader of the Opposition in the Senate) (14:45): My question is to Senator Johnston, the Minister for Defence. Who authorised the use of a South Australian Liberal Party banner as a backdrop at RAAF Base Edinburgh in Adelaide for a joint press conference held by the Prime Minister and the South Australian opposition Liberal leader, Steven Marshall, on Thursday, 13 March, just two days before the South Australian election; and does the minister approve of the Prime Minister standing in front of a Liberal Party banner— The PRESIDENT: Order! Order, Senator Conroy! Holding up pictures is disorderly— Senator CONROY: which included the Liberal Party logo, Liberal Party slogans and the South Australian Liberal leader's Twitter handle, while on a Defence Force base?
