Senator AYRES (New South Wales—Minister for Industry and Innovation and Minister for Science) (14:38): Well, because it is the cheapest way of modernising Australia's electricity system, and, as we go through the challenging national interest task— Opposition senators interjecting— The PRESIDENT: Minister Ayres, please resume your seat. When Senator Canavan asked that question, you could have heard a pin drop in this place. The minute the minister got to his feet, those on my left thought it was time to interject. It is not. If you can't listen in silence, leave the chamber. Minister, please continue. Senator AYRES: We saw what the alternative might be; we had a little glimpse into what the alternative might look like, over the miserable decade—the Abbott-Turnbull-Morrison decade—of indolence and failure on energy policy. We saw what that did for Australians. That wrecking impulse that is so fundamental to your approach in this area of policy hurts ordinary Australians. It costs jobs. It cost jobs when you were in government. The only difference now is that the position that the Liberals and Nationals have adopted is more extreme and more likely to lead to dislocation and disinvestment than in the last decade. The PRESIDENT: Senator Canavan, first supplementary? Senator McKenzie interjecting— The PRESIDENT: Senator McKenzie, your constant interjections are incredibly disorderly, and they are rude towards the orders that I am giving. As I said, if you can't listen quietly and in silence, leave the chamber. Senator Canavan, first supplementary?
