In recent weeks, however, local media reports have suggested he was closer to marshalling the numbers needed for victory.
Ms Gillard became Australia's first female prime minister in June 2010, ousting Mr Rudd amid concerns over his environmental and taxation policies.
But many voters were angered by the move and the general election she subsequently called delivered a hung parliament.
Ms Gillard then formed a government that relies on independents for a majority, but public support for her has remained low.
Mr Rudd, meanwhile, served as foreign minister in her cabinet until his failed challenge in 2012.
In recent weeks, speculation that his supporters could seek a leadership change ahead of the election had mounted.

The general election is due to take place on 14 September.
