Senator WONG (South Australia—Minister for Finance and Deregulation) (14:19): I am happy to take a question from a Western Australian senator about the Olympic Dam expansion—not a South Australian, of course. The South Australian Liberal senators are clearly not interested in the expansion of Olympic Dam, which is an important project for Australia. Senator Cormann: Mr President, a point of order in relation to the requirement to be directly relevant: how can the minister's abuse on this issue in response to the question be directly relevant to the question? The PRESIDENT: I do draw the minister's attention to the question. The minister has 45 seconds remaining. Senator WONG: I am very happy to talk about Olympic Dam. As I said in answer to the question from a Queensland senator, Senator Brandis, BHP Billiton has made very clear the reasons for the shelving of the expansion. Unlike those opposite, we are deeply disappointed by that decision. Whilst this may not be an issue for Senator Cormann, it is an issue for South Australians. We do not thank people trying to make a political game out of this issue. We do not thank the Leader of the Opposition for engaging in a self-interested, dishonest and disgraceful scare campaign around this issue. We want to get on with the job of working with BHP to seek to ensure that this expansion can go ahead.
