Mr HUNT (Flinders) (15:14): My question is to the Prime Minister and in fact follows on from the answer by the Minister for Climate Change and Energy Efficiency. I refer the Prime Minister to her 10 July press release that promised updated Treasury modelling would be available ahead of the introduction of the carbon tax legislation precisely because the modelling wrongly assumes a $20 carbon tax when the actual tax is 15 per cent higher at $23. Given that the government has now introduced that legislation without the updated modelling, why has she broken her promise and when will she keep it?
