Senator LUDWIG (Queensland—Minister for Agriculture, Fisheries and Forestry and Minister Assisting on Queensland Floods Recovery) (14:56): Again, it is a very confused question. Senator Abetz: No, it's not. Senator Brandis: The price! The price! Senator LUDWIG: Well, one of the difficulties for Senator Macdonald is that it is an attempt to link two different parts together. The carbon price projections in the budget are the result of extensive Treasury modelling. That is a given. The government stands by—and I have continued to say that throughout this confused questioning by Senator Macdonald—the extensive modelling carried out by Treasury. Their work has proven to be accurate since the price came into effect, which those opposite continue to complain of and decry. Senator Ian Macdonald: Mr President, I raise a point of order on direct relevance. Again, I point out that I have asked Senator Ludwig what information he has that leads the government to believe that the $8 European price today will increase to $29. I am not interested in what he is rattling on about. Can he answer the question, please? The PRESIDENT: There is no point of order. The minister is answering the question and the minister still has 19 seconds remaining. Senator LUDWIG: Thank you, Mr President. I continue to thank Senator Macdonald for his confused question. He remains confused, I have no doubt, notwithstanding even the question he asked. The point is the Treasury modelling is what the government stands behind. It has been effective. It has worked. It has clearly already predicted the price on electricity. (Time expired)
