Fiji-born wing Eto Nabuli has been ruled out of the Rugby Championship.
Nabuli is struggling with an ankle injury.
He made his test debut in June.
Nabuli was included in the Wallabies Rugby Championship training squad alongside Samu Kerevi, Sefanaia Naivalu and Marika Koroibete.
Karmichael Hunt has also been ruled out of the Wallabies' opening Bledisloe Cup tests after undergoing ankle surgery.
The June test debutant is expected to be sidelined for two months, which means he will miss Australia's first four Rugby Championship clashes including the first two Bledisloe Cup encounters.
The return of Kurtley Beale from overseas will greatly soften the blow as he was expected to take over at inside centre after Hunt started there last month.
