Senator BRANDIS (Queensland—Deputy Leader of the Opposition in the Senate) (14:00): My question is to Senator Wong, the Minister representing the Minister for Climate Change and Energy Efficiency. I refer the minister to the repeated warnings of BHP Billiton about the effect on the viability of the Olympic Dam project of the government's policies and, in particular, the warning from the chairman of BHP Billiton, Mr Jacques Nasser, who said on 16 May: I cannot overstate how the level of certainty about Australia's tax system is generating negative investor reaction. People don't know where they are going. Given the government failed to heed the warnings about the disastrous impact of its mining tax and carbon tax on Olympic Dam, will the minister now apologise to the people of South Australia for costing them a $30 billion mining investment, the most significant in the state's history, and costing South Australia over 13,000 new jobs?
