Senator COLBECK (Tasmania) (14:57): My question is to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. Given that there are only 11 days until the carbon tax is introduced, can the minister explain why the government has not undertaken any specific study or analysis into the effects of this tax on Australia's horticultural sector? How does the minister respond to findings in the report commissioned by Horticulture Australia that the impact of the carbon tax on horticultural producers is likely to represent a significant reduction in farm profits?
