Western Australia all-rounder comes into the 13-man party in place of Chadd Sayers
Australia have added Mitchell Marsh to their squad for the third Ashes Test in Perth next week.
The Western Australia captain comes into the 13-man party in place of South Australia seamer Chadd Sayers, who did not get a run-out at the Adelaide Oval in the second Test.
Marsh has been in good form with bat and ball in the Sheffield Shield and gives Australia the option to pick an extra all-rounder at a ground which has been favourable to batsmen in recent months.
Having undergone reconstructive shoulder surgery this year, Marsh has recovered well and posted a century against Queensland at the WACA last month.

His presence in the squad will put pressure on Australia's current number five, Peter Handscomb, who has averaged little more than 20 during the current series against England.
Australia go to Perth 2-0 up in the Ashes after completing a 120-run victory over England on Wednesday.
The third Test is due to get underway on Thursday, December 14.
Australian Test squad: David Warner, Cameron Bancroft, Usman Khawaja, Steve Smith (capt), Peter Handscomb, Shaun Marsh, Mitch Marsh, Tim Paine, Mitchell Starc, Pat Cummins, Josh Hazlewood, Nathan Lyon, Jackson Bird.
