Australia have named an unchanged 15-man squad for the remainder of the Ashes ahead of Test matches in Melbourne, Sydney and Hobart.

Pace pair Pat Cummins and Josh Hazlewood will re-join the squad after both missed the second Test in Adelaide.

Cummins was ruled out after being a close contact of a confirmed COVID-19 case, while Hazlewood missed due to a side injury.

The duo will come back into contention to replace Jhye Richardson and Michael Neser who stepped up in their respective absences in Adelaide.

Opening batsman Marcus Harris has been retained in the squad despite managing only 38 runs in four innings during the series. Usman Khawaja remains the back-up batsman in the squad and could still displace Harris.

The Australians will have rest days on Tuesday and Wednesday before assembling in Melbourne on Thursday ahead of the Boxing Day Test from Sunday at the MCG.

Australia leads the series 1-0 and is in a strong position to claim victory on the final day in the second Test in Adelaide on Monday.

Australia Test squad: Pat Cummins (c), Steve Smith (vc), Alex Carey, Cameron Green, Josh Hazlewood, Marcus Harris, Travis Head, Usman Khawaja, Marnus Labuschagne, Nathan Lyon, Michael Neser, Jhye Richardson, Mitchell Starc, Mitchell Swepson, David Warner
