Senator XENOPHON (South Australia) (14:27): My question is to the Minister for Finance representing the Treasurer. Last night's budget announced $70 billion of infrastructure commitments, but no new commitments for new projects in South Australia. Only $3.1 billion of the $70 billion is for South Australia. That is only 4.5 per cent, well under South Australia's population figure of 7.1 per cent. Government senators interjecting— Senator XENOPHON: Stop laughing, it is not funny. When we have 12 per cent of the nation's road network, for instance, why is South Australia receiving so much less for infrastructure projects, being short-changed by some $2 billion— The PRESIDENT: Senator Ludlam, is there a point of order? Senator Ludlam: Mr President, I am sitting adjacent to Senator Xenophon and I cannot hear him over the chaos that is happening on this side of the chamber. Can you call them to order? The PRESIDENT: I remind all senators, particularly those on my right in this instance, that I need to hear the question as well as the minister. Senator XENOPHON: The question is: why is South Australia receiving so much less for infrastructure projects, being short-changed by at least $2 billion, particularly when South Australia's unemployment rate is the highest in the nation?
