Macdonald, Sen Ian

Senator IAN MACDONALD (Queensland) (14:45): Mr President, I ask a supplementary question. Honourable senators interjecting— The PRESIDENT: Order! One moment, Senator Macdonald. On both sides, Senator Macdonald is entitled to be heard. Senator IAN MACDONALD: I thank the minister very much for that very concise and clear answer, which we are particularly interested in. What disclosures and assurances have you sought from Dr Ricketson about the extent of the contact between him and the Australian Greens, either prior to his appointment to the media inquiry or subsequent to it?
