Senator AYRES (New South Wales—Minister for Industry and Innovation and Minister for Science) (14:26): Senator, thank you very much for that supplementary question. What you can see from the caterwauling from down here, there and there is that they haven't learnt, they haven't learnt and they haven't learnt from what happened in the last election. We are about delivering for young Australians and Australians who are trying to find their own home, whether it's to rent or whether it's to buy. An opposition senator interjecting— Senator AYRES: I will get to you in a moment, sunshine. Your contribution— The PRESIDENT: Minister Ayres, I'm not sure who that was directed to, but it was inappropriate, so please withdraw. Senator AYRES: I will withdraw unreservedly. Senator Ruston: Could I seek your ruling on whether a withdrawal is sufficient or whether an apology may not be more appropriate. The PRESIDENT: Senator Ruston, I wish there were no name-calling in this place, because it's disrespectful. Minister Ayres has withdrawn. Senator AYRES: Really dragging us back to the dark ages of housing policy. We know what demand-side-only housing policy meant. It meant rising prices. Senator Bragg said—this was probably on Sky last night—it was possible the approach he helped to craft did too much on the demand side and could have pushed up prices. The relentless negativity—I'll come to the rest of it in a tick, I suppose. The PRESIDENT: Thank you, Minister Ayres. Senator McKenzie: You have time to practise your answers. The PRESIDENT: Senator McKenzie, you do not have the call. If you can't listen in silence, leave the chamber. Senator Dowling, second supplementary?
