Senator JACINTA COLLINS (Victoria) (14:33): My question is to the Assistant Treasurer, Senator Sinodinos. I refer the Assistant Treasurer to his previous answers concerning his dealings with Australian Water Holdings. Is the Assistant Treasurer aware that company treasurers are required to be honest and careful in their dealings, to know what their company is doing at all times and to ensure that their company keeps proper financial records? As a director of Australian Water Holdings—indeed, as chair—was the Assistant Treasurer honest and careful in his dealings, did he know what his company was doing at all relevant times and did he ensure that his company kept proper financial records? The PRESIDENT: As I have ruled on other occasions this week on questions similar, the minister need refer to only those matters that pertain to the portfolio. Senator Ian Macdonald: Mr President, I raise a point of order. Senator Sinodinos does not need my help, but clearly it is your role to rule out of order questions which clearly have no relevance whatsoever to this parliament or to this portfolio. I ask you, Mr President, not to ask Senator Sinodinos to answer on his portfolio but simply to rule the question out of order. The PRESIDENT: There is no point of order. I have made it quite clear that the minister need only address matters that pertain to the minister's portfolio.
