Australia has named its 15-member squad for the fifth Ashes Test against England in Sydney, commencing January 4. Steve Smith will continue to captain the team in Pat Cummins' absence, who is being rested to manage workload and prepare for the T20 World Cup. Usman Khawaja retains his place in the squad despite recent injury concerns and mixed performance in the ongoing series, where he has scored 153 runs in three matches.
