Senator MASON (Queensland) (14:10): My question is to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. I refer the minister to a Bligh government commissioned report tabled in the Queensland parliament yesterday showing that my home state's growth will be cut by 2.76 per cent to the year 2020 under a carbon tax compared to federal Treasury's initial estimate of a reduction of just 0.3 per cent. How can the minister claim that this tax is good for Queensland and for Australia?
