Senator WONG (South Australia—Minister for Finance and Deregulation) (14:01): I thank the senator for his question. I again make the point that he may have a crystal ball as to what the world will look like in 2015, 2016, 2017 and 2018, but I doubt it. What I would say is that we will update our budget figures in the usual way in the budget, just as we did in the midyear review and just as we did in the budget handed down last year. We will do just as Peter Costello would in the same circumstances: update the budget figures. But I can tell you this: the one difference—there are a number—the one very important difference between our plan and yours is that we can pay for ours and we can fund it, but you have a plan which will double the effective carbon price. I know you do not want to hear this, Senator Birmingham, it is absolutely embarrassing. Senator Birmingham: Mr President, a point of order going to the matter of direct relevance: the question was a very specific and carefully worded question. The question was about what the impact on government revenue would be from a lower than assumed world carbon price. It did not go to any other policies, it did not go to any of the material that the minister is canvassing. I ask you to draw the minister to the question. The PRESIDENT: There is no point of order at this stage. I am listening closely to the minister's answer. The minister still has 59 seconds remaining in which to answer the question. Senator WONG: I again remind the opposition that our entire carbon price package, the clean energy future package, is factored into the budget bottom line, which shows the budget returning to surplus in 2012-13. That is something you have walked away from. Senator Birmingham, I can understand your taking a point of order when we remind Australians that your policy would cost them more. Your policy would cost them more—$1,300 per family, per household, every year, being taken from working families and given to those businesses that emit carbon. Yes, of course you will take a point of order! Senator Birmingham: Mr President, you have reminded the minister that she had 59 seconds left, at that stage, to address the question. She now has 23 seconds left to become directly relevant to the question. I do ask you, please, to ensure that she is directly relevant to the question about the impact of a lower world carbon price on government revenue. Senator Chris Evans: Mr President, on the point of order: Senator Wong is directly trying to deal with the senator's question. The fact that she is engaged in beating him around the ears may be cause for him to complain, but it is not a point of order. The PRESIDENT: That is not a point of order, Senator Evans. I do remind the minister of the question. The minister has 23 seconds to address the question. Senator WONG: Thank you, Mr President. As I have said now on a number of occasions, the carbon price package, the clean energy future package, is reflected in the bottom line. We have funded it. We will update our figures for the outer year, which is the 2015-16 year, in the usual way in the coming budget. One thing I can say for absolute certainty is that ours will add up; yours will not.
