Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:33): Mr President, I have a further supplementary question. I refer to comments from a Liberal frontbencher: It’s very difficult to imagine Heffernan didn’t offer these views to Credlin and Tony Abbott, I ask again: was the Prime Minister or his office aware of Senator Sinodinos's dealings with Australian Water Holdings before he appointed him to the ministry? This is a question about the Prime Minister's knowledge.
