Senator WONG (South Australia—Deputy Leader of the Government in the Senate and Minister for Finance and Deregulation) (14:12): I thank the senator for his question. I have been waiting for a question from Senator Cormann, and it is very pleasing that we finally have one. He will know, of course— Senator Ian Macdonald: Could you try answering it then, for a change? Senator WONG: Oh, you're still here, are you? Honourable senators interjecting— The PRESIDENT: Order! Interjections are disorderly, on both sides. The minister is entitled to be heard in silence. Senator WONG: Senator Cormann traversed this in great detail in estimates. Senator Ian Macdonald interjecting— Senator WONG: He's reminding us he's still here. Senator Cormann: There have been some boat arrivals since then. The PRESIDENT: Order! You have asked the question. The minister should have the opportunity to answer the question. The minister has one minute and 25 seconds. Senator WONG: As I was saying, this matter was traversed in great detail in the budget. The opposition would know that we did provision additional funds for asylum seeker management in the budget. The methodology for irregular maritime arrivals is set out at statement 6 of the budget papers. It is transparently heavily influenced by occupancy levels across the immigration processing network, which are determined by the number of IMAs already in Australia awaiting resolution of the protection visa applications, operational decisions, length of time taken to resolve asylum claims and so forth. So the point is: we have been transparent in the budget about the methodology associated with IMA costs. Senator Cormann: Mr President, I rise on a point of order in relation to the requirement for the minister to be directly relevant to the question. The question was not one about methodology in the budget, which we know. The question was whether the minister stands by the expenditure forecast, the expenditure projections that were made at budget time. The minister has not got anywhere near answering the question as to whether she stands by the predictions that were made in the budget in relation to illegal boat arrivals. Senator Jacinta Collins: On the point of order, Mr President: of course methodology is relevant to that question. The PRESIDENT: There is no point of order at this stage. Senator WONG: The methodology is very relevant to the cost estimates—it is how the costs are calculated. In relation to this or any other issue, budget estimates are always reviewed at each budget update. Senator Cormann: Do you stand by it? Yes or no. Answer the question. Senator WONG: Have you finished heckling? Seriously, why do you bother asking questions? Why don't you both ask and answer the question yourself? Senator Cormann interjecting— Senator WONG: You like the sound of your own voice so much— The PRESIDENT: Order! If you have asked a question, it does not help if you repeatedly override the minister with interjections throughout the answer. You have the opportunity now to ask a supplementary question. Senator Cormann: It would help, of course, if the minister answered the question. The PRESIDENT: Order! There is no debate. Ask your question.
