Mr President, I ask a further supplementary question. Last week the Treasurer made a speech on carbon tax but did not provide any modelling. When will the modelling used to justify the carbon tax be made available, and will it differ from the old CPRS modelling that claimed a carbon tax will reduce growth and aggregate productivity, produce temporary unem­ployment of up to 10 years and see real wages fall by 4.2 per cent?
