Senator McALLISTER (New South Wales—Minister for Emergency Management and Minister for Cities) (14:30): Thanks very much for the question, Senator Roberts. In terms of costings, we take the advice of the experts. We've had this conversation more than once, in fact, in the context of estimates and in other forums. AEMO works through a range of scenarios and configurations for the National Electricity Market and makes an assessment of the optimal pathway to meet our energy requirements at the optimal cost. They do consider, of course, the capacity factors of the different options that are available to us. There's actually quite a lot of work to do. The truth is that we inherited a mess in the energy system. When we came in, the average wholesale energy price was $286 a megawatt hour— The PRESIDENT: Minister McAllister, please resume your seat. Senator Roberts? Senator Roberts: Point of order on relevance: standing order 72(3)(c) says that answers shall be directly relevant to each question. Can we get on to whether or not Labor is aware— The PRESIDENT: Senator Roberts, as I've reminded other senators in this place, make your point of order but don't follow it up with a statement. The minister is being directly relevant to the points of your question. Minister McAllister, please continue. Senator McALLISTER: Thanks, President. As I was saying, we came to government with a lot of work to do because the previous government had 22 energy policies, all of which failed. None of them landed. During the period when they were in government, four gigawatts of dispatchable capacity left the system and only one came on. We actually need to take steps to sort that out, because the previous government was repeatedly warned by the market operator that a failure to deal with the impending closure of coal-fired power stations was going to cause a reliability problem. We have sought advice from the experts at the market operator to help us design the policy settings that will actually allow us to replace that exit in capacity. It's a lot more than anything that was ever delivered by the people opposite. The very great shame is that, for a person who I know seeks to represent people in Queensland, you show an odd lack of interest in the opportunities that come about as a consequence of making and facilitating these investments, which have the potential to bring jobs and new industry to the communities that you claim to care about. The PRESIDENT: Senator Roberts, first supplementary?
