Senator AYRES (New South Wales—Minister for Industry and Innovation and Minister for Science) (14:53): The word 'we' in that question is doing a lot of work; it really is. When you say, 'We signed up,' who's the 'we' that we're talking about? It's Mr Taylor, right? Mr Taylor, Ms Ley, Mr Morrison, Mr Joyce—all of you. Opposition senators interjecting— Senator AYRES: I couldn't be more directly answering that question. The PRESIDENT: Senator McDonald? Senator McDonald: The question is: how much higher will prices go? The PRESIDENT: That was part of the question, Senator McDonald. There was a preamble, and the minister is being directly relevant. Senator AYRES: I'm reminded of Muhammad Ali, who said: 'Me. We.' We—all of us. If only that small moment of policy coherence could extend its way through, just imagine what would happen. Poor old Senator Canavan over there, who's sort of running this— (Time expired) The PRESIDENT: Senator McDonald, second supplementary?
