My question is for the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. Senator, with the Labor-Green alliance's carbon tax now responsible for the death of Fairfax, can the government produce modelling to prove that the carbon tax did not cause or contribute to Victoria's earthquake on Tuesday evening? Furthermore, what do you have to say to those people who suffered distress and damage in the Victorian earthquake, and will you guarantee there will be no further earthquakes in Victoria following the carbon tax?
