Ms MACKLIN (Jagajaga) (14:13): My question is to the Prime Minister. According to the Liberal Party, NATSEM is Australia's foremost modelling consultant. Given that independent NATSEM modelling shows that a typical family will be more than $6,000 a year worse off because of the Prime Minister's budget, can the Prime Minister outline the assumptions in the government's own modelling that shows the impact of the government's changes on families, and when will the Prime Minister release the Treasury's modelling? Mr Burke: Madam Speaker, a point of order under standing order 100(d)(i): a statement was made about the belief of the Liberal Party, and I ask that you insist that the questioner authenticate that. The SPEAKER: Well, I am sorry, but I regret to inform the Manager of Opposition Business that he has just performed a home goal. That makes the question out of order. Mr Dreyfus interjecting— The SPEAKER: The member for Isaacs will remove himself under 94(a). The member for Isaacs then left the chamber. Mr Burke: Madam Speaker, a point of order: with respect, you cannot rule a question out of order for being within the standing orders. I raised a standing order— The SPEAKER: The member will resume his seat or join the member for Isaacs.
