Senator WONG (South Australia—Minister for Finance and Deregulation) (14:34): Let us understand what the question is proposing. The opposition is suggesting that another reason to oppose this bill, to which they are already so implacably opposed, is because of something which may or may not happen between 2020 and 2050. We know something that is likely to happen in the decades ahead if the world, including Australia, does not act on climate change—that is, climate change will worsen and the economy in this nation and globally will be hit by that. Those on that side— Senator Brandis: I rise on a point of order on direct relevance, Mr President. The question was specific: whether or not there was an assumption and what was the amount of the reduction. The minister has done nothing but critique the question. She has not attempted to answer the question. She has not approached the question, let alone been directly relevant to it. You should bring her to the question. The PRESIDENT: I believe the minister is answering the question. Senator WONG: As I said, the Treasury modelling is quite transparent in the various assumptions it makes. As I have outlined, it makes assumptions consistent with the approach taken by analogous modelling exercises such as those undertaken by the OECD. But the point is the opposition do not care about the modelling. (Time expired)
