Wallabies coach Dave Rennie has confirmed a 35-player squad for the Tests to play South Africa in Adelaide and Sydney.
Flyhalf Bernard Foley has earned a call-up, last featuring in the 2019 Rugby World Cup, following a season-ending injury to Quade Cooper.

Foley's inclusion comes as James O'Connor was left out despite starting in their previous Test against Argentina.
He is joined by NSW Waratahs backrower Langi Gleeson, whose impressive Australia A campaign has rocketed him into his first Wallabies squad.
Gleeson and Reds fullback Jock Campbell are the two uncapped players in the squad.
“After a tough two weeks in Argentina we're extremely pleased to be able to welcome a few men back into the mob this week," Rennie said in a statement.
"To have their experience on deck will be valuable in what's going to be a massive challenge coming up against South Africa two weeks in a row."
This includes winger Andrew Kellaway (hamstring) as well as props Scott Sio (arm) and Angus Bell (toe), making their return having missed the tour of Argentina due to injury.
They are joined by Hunter Paisami, Dave Porecki (both concussions) and Allan Alaalatoa (personal reasons).
"We know how important these matches are and we'll be working hard to make sure we put out performances that earn the respect of our supporters," Rennie added.
The Wallabies will open their campaign in Adelaide on August 27 as part of a double-header as the Wallaroos take on the Black Ferns.
This is followed by both teams heading to Sydney on September 3, set to be the first International match at the new Allianz Stadium.
