Senator JOYCE (Queensland—Leader of The Nationals in the Senate) (14:49): The minister has been unable to answer question 1 of— The PRESIDENT: It is not a debating time; it is time to ask the question. Senator JOYCE: It is not even a question time when she cannot answer them. The PRESIDENT: Senator, you have the chance to ask the question. If you want to ask the question, ask the question. It is not debating time. Honourable senators interjecting— The PRESIDENT: Order, on both sides! Senator JOYCE: She says more sitting down than standing up. You are just incompetent. That is the problem. The PRESIDENT: When there is silence, Senator Joyce, you will get the call. Senator Joyce. Senator JOYCE: I ask a further supplementary question. Why does the government need a $50 billion buffer zone if it only expects debt to go above $250 billion for temporary periods and you have the temporary revenue deficits act to deal with it in those periods? Honourable senators interjecting— The PRESIDENT: When there is silence on both sides, we will proceed. I remind honourable senators that the time to debate these issues is after question time. The minister has call.
