Senator MADIGAN (Victoria) (14:43): My question is to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. Minister, in light of Professor Ross Garnaut's statement that the Latrobe Valley was likely to be the hardest hit area in the country, can the government explain why the Australian people should believe Treasury figures used to form its carbon tax policy when vitally important socioeconomic impact studies, such as the one the government should be commissioning for the Latrobe Valley after consistent local community protests, have been ignored and the detrimental impacts on industry and the communities have not been considered in its modelling?
