South Australia’s Premier-Elect Peter Malinauskas vowed to be a “pro-business” leader who would work hand-in-hand with private enterprise to expand the overall economy, but one of his first moves is to try to end a $2.1 billion rail network privatisation contract signed by the now-vanquished Marshall government.

Mr Malinauskas promised on Sunday that business would “have a seat at the table” and he would regularly invite senior business people in once a month to talk to his state cabinet, as Steven Marshall quit as SA Liberals leader after a heavy loss in the state election.
