Australian Prime Minister Julia Gillard and the man she ousted, Kevin Rudd, are to contest a party leadership vote.
Ms Gillard called the vote after Mr Rudd's supporters sought to force a party meeting to hold a ballot.
The vote is taking place at 19:00 local time (09:00 GMT) on Wednesday. Both contenders have committed to stepping down from politics if they lose.
Mr Rudd told reporters that he intended to run. "For the nation's sake I believe it's time for this matter to be resolved," he said.
