Australia's cricket squad has held its final training session at the Sydney Cricket Ground, with the fifth and final Ashes test against England starting tomorrow.
Shane Watson and Ryan Harris both bowled in the nets this morning in a bid to prove their fitness.
All-rounder Watson is in doubt because of a groin strain, while fast bowler Harris has also been under an injury cloud with knee soreness and a foot blister.
The Australian captain, Michael Clarke, hasn't ruled out making changes to the side, and says he expects England to recall wicket keeper Matt Prior, who was dropped for the fourth test in Melbourne.
Clarke says England missed Prior's experience and capable batting in the last match.
England have already lost the Ashes series, with Australia holding a 4-0 lead heading into tomorrow's Test.
