Senator JACINTA COLLINS (Victoria) (14:39): Mr President, I ask a further supplementary question. I note, again, that the Assistant Treasurer has answered questions previously before the Senate with respect to Australian Water Holdings. In that respect I ask: did the Assistant Treasurer know who owned interests in Australian Water Holdings; and, if not, why not? The PRESIDENT: The Assistant Treasurer, again—in so much as it applies to the minister's portfolio.
