Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:56): I thank Senator Birmingham for his question. I don't know the answer to that off the top of my head. I'm very happy to speak to the minister for resources to get those accurate figures. I am aware that South Australia has very significant levels of uranium, and I'm very pleased to hear that it looks like BHP is taking some steps to increase its extraction of uranium, gold and copper. Senator Ruston: Safely, I hope. Senator FARRELL: Yes, I'm sure it will be a safe extraction. But, no, South Australia does have significant amounts of uranium, and of course we export that uranium safely to the world. The PRESIDENT: Senator Birmingham, first supplementary?
