Mr TAYLOR (Hume) (14:31): Thank you, Mr Speaker, and congratulations on your appointment. My question is to the Treasurer. Will the Treasurer outline to the House the importance of keeping taxes low to ensure that we have a globally competitive business environment? What would be the impact of alternative approaches? The SPEAKER: The member for Charlton. I am sorry, the member for Rankin. You look alike. Honourable members interjecting— Dr Chalmers: On a point of order, Mr Speaker. I do not know who does worse out of that, Mr Speaker. If your words from yesterday are to have any true meaning, you will reflect on page 555 of Practice, which is very explicit about asking about opposition policies. Ms Plibersek interjecting— The SPEAKER: I am ready to respond when the member for Sydney ceases interjecting. The member for Charlton—I am sorry the member for Rankin—I am sorry I am not doing that deliberately; I am really not. The member for Rankin is making a similar point. As I pointed out, former Speaker Jenkins, back in 2008 and again in 2012, addressed some of these matters. He had this to say: 'It should be done in a careful way'—I am quoting former Speaker Jenkins—'and in the interests of a free-flowing debate I am going to hear the minister's answer. I want to monitor the minister's answer, but I think a discussion of alternative policies is important in a free-ranging debate. Otherwise it is really going to curtail the answers of ministers.' Similarly, I do not want to curtail the asking of questions, either.
