Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:45): Thank you for that question, and thank you for the opportunity to outline the difference between our political parties about climate change, net zero and renewable energy. We on this side recognise the imperative of transitioning the Australian economy. We on this side recognise the opportunity that we have. We on this side recognise the importance of reforming the energy system. We on this side recognise the importance of policy certainty. On that side, what we know is that they have had decades of internal fighting about climate policy, and they're still not over it. Even though Ms Ley has made really clear her view on these issues, everyone, from Senator Cash to Senator McKenzie, is showing a complete lack of loyalty to their leader and, frankly, not listening to their voters. Senator McKenzie: A point of order on direct relevance. I don't argue with the Labor Party's commitment to this policy; I want them to release the true cost. The PRESIDENT: The minister is being relevant. Thank you, Senator McKenzie. Senator WONG: I was interested, Senator, to see some of the commentary, including from the Western Australian Liberal leader and in the papers, about coalition voters and how most coalition voters are actually wanting the coalition to take a mature and rational approach to this policy dilemma. Senator Cash: Lower the cost. Senator WONG: I will take that interjection—'Lower the cost.' If you really think that coal-fired power is the lower cost, after you have seen coal-fired power exit the system and you have seen how the unreliability of ageing coal-fired power stations has increased costs to Australians, and you really think that nuclear is the way forward—well, I think everyone can look at the coalition's policy and see it is ideological and irrational. The fact is that we have the cheapest possible policy, unlike you. Senator McKenzie interjecting— The PRESIDENT: Senator McKenzie it is one thing to quote language, which, quite frankly, I'd rather you didn't; it is quite another to shout it across the chamber. Please withdraw. Senator McKenzie: On behalf of the Prime Minister and myself, I withdraw. The PRESIDENT: Senator McKenzie, you shouted it across the chamber. Senator McKenzie: I withdraw. The PRESIDENT: Senator McKenzie, first supplementary?
