Senator WONG (South Australia—Deputy Leader of the Government in the Senate and Minister for Finance and Deregulation) (14:28): There are a lot of subclauses in that question, but I think the first point I would make— Senator Ian Macdonald: The old senator couldn't manage at Copenhagen but she might be able to handle this. The PRESIDENT: Order! Senator WONG: It is so tempting, when Senator Macdonald says things like that. But I am not going to give him the benefit— The PRESIDENT: Order! Senator Wong, ignore the interjections— Opposition senators interjecting— The PRESIDENT: Ignore the interjections and address the chair. Senator WONG: I am trying, Mr President. I am trying. Senator Abetz: You are very trying. Senator WONG: The first point I would make is that I do not believe that the senator's articulation of what he believes I said is correct and I would like him to consider the Hansard. The second point I would make is to refer back to my first answer, which is that it is perfectly normal for governments to update any estimate, whether it is this or any other, and we have set out the methodology in the budget papers.
