Senator WONG (South Australia—Deputy Leader of the Government in the Senate and Minister for Finance and Deregulation) (14:25): Thank you to Senator Cormann for the question. It is the case that variations to budget estimates are made, and they occur across a range of programs. The senator has mentioned one. There are others, from memory, in higher education and in some areas of the FaHCSIA portfolio, where we had higher expenditure than expected and, in some cases, lower expenditure. The senator would know that it is a normal part of budgeting to update estimates as and when further information comes in. I think one of the suggestions or implications in the question is that somehow that is untoward. Every government updates its estimates at every budget update in line with information which is received by departments. In relation to the IMA costs, or irregular maritime arrival costs, as the senator knows—and I would refer him to my answer yesterday—the government is being perfectly transparent about the assessment of these costs. Senator Abetz: Oh, please! Your transparency is ludicrous. Senator WONG: We for the first time— Senator Abetz: Ludicrous! Senator WONG: Senator Abetz, maybe you could wait until you know something about something before you say something, because the reality— Honourable senators interjecting— Senator WONG: The reality is— Senator Abetz: I am so hurt! The PRESIDENT: Order! Senator WONG: I am being good today, Mr President. This is me being good. See, I am smiling—so I am being good! The PRESIDENT: Order! Senator Wong, Ignore the interjections. Opposition senators interjecting— Senator WONG: No, I am being kind today. Senator Abetz, you may like to know that this is the first time, in my memory—and I could be wrong—that these methodologies have actually been published in the budget papers, and we did so because we thought it was important that we laid out the methodology for the assessment, and that is what we have done.
