Climate change was to be the undoing of Turnbull the first time around. Kevin Andrews moved a spill on November 26, 2009 and lost. The next day Tony Abbott challenged but then declared he would back Joe Hockey. But when Hockey refused to oppose a carbon emissions trading scheme, Abbott stood at the December 1 ballot and defeated Turnbull by one vote.

Labor's Kevin Rudd became the second Australian prime minister to be dumped while in office when Julia Gillard rolled him in 2010 just before an election. She claimed government after 17 days of negotiation to win crossbench support.

Three years later, Australia's first woman prime minister was gone when Rudd finally took his revenge after a failed 2012 coup attempt. In March 2013, Gillard called a spill but no-one challenged. Four months later on June 26, Gillard called Rudd's bluff again at 4pm and was gone in a caucus vote a couple of hours later. Rudd and Labor lost the election as expected.

Abbott led the Liberal-National coalition to a storming victory over Rudd's Labor in 2013. He called a spill in February 2015, but it wasn't until September that Malcolm Turnbull finally moved after Abbott had lost 32 Newspolls in a row.
