Thank you, Mr Speaker. In last night's budget speech, the Treasurer announced $75 billion for nation-building infrastructure and financing, but only $3.1 billion of this money was earmarked for South Australia. Based on our population, an equitable share for South Australia would have seen us receive more than $5 billion of infrastructure money. Given South Australia is being short-changed on nation-building infrastructure, will the federal government at least guarantee that Australian steel will be used in its national infrastructure projects, and in particular South Australian steel for its proposed rail projects?
