Senator AYRES (New South Wales—Minister for Industry and Innovation and Minister for Science) (14:45): Thank you, Senator Babet; I do sincerely thank you for this question. I reflect that it's not necessary for Senator Canavan or Senator Antic or Senator Nampijinpa Price to ask this question, because it's all one team over there. On the question of policy certainty around energy, on the approach that the Australian government takes on climate change, and on rebuilding and modernising our electricity system, there's complete unanimity across all of that show over there, who didn't learn the lesson in 2022 and certainly didn't learn the lesson in 2025. The PRESIDENT: Senator Ayres, I am going to draw you back to the question. Senator Wong: President, respectfully, could I submit that the question does go to net zero and that the minister's wind-up, albeit quite a lengthy one, actually is about the policy position on net zero. The PRESIDENT: Thank you, Senator Wong. I did allow some leniency for Senator Ayres to get to the question. When he hadn't in what I thought was a timely manner, I drew the question to his attention. Minister Ayres. Senator AYRES: You were very lenient, President—very lenient indeed! And I was getting ahead of myself. Net zero, for Senator Babet's information—through you, President—is really a basic maths concept. I just want to set it out to provide a little bit of clarity for the team over there. We will have reached net zero emissions when the amount of greenhouse gas that we emit into the atmosphere is no more than what is removed. Senator Babet and Senator Cash have asked—I should have included you, Senator Cash, in the list of potential askers, the silly-billies over there on energy policy— Senator Cash: Australians are paying more. Senator AYRES: If you're inclined to interject, Senator Cash, perhaps you could explain how it is that you've been defying your leader and repudiating her authority already. On the first weekend of a sitting fortnight, you're up and about— (Time expired) The PRESIDENT: Senator Ayres, I remind you to direct your comments to the chair. Senator Babet, first supplementary?
