September 14 was a tumultuous day for Australian politics. At 4pm Malcolm Turnbull announced he was challenging Tony Abbott as leader of the Liberal Party, at 6pm Tony Abbott spoke out, at 9.15 they had a vote, and by 9.45 there was a new leader of the Liberal Party. Is this indicative of a larger trend? And what changes might Malcolm Turnbull have in store for his party and for Australia? I spoke to Melbourne University’s Associate Professor Sarah Maddison about this.
