Michael Hooper is back in the Australia squad for the upcoming tour of Europe, but James Slipper will retain the captaincy.
Hooper has not played since he withdrew from the Wallabies squad on the eve of their Rugby Championship opener against Argentina in August.
The flanker stated that he was not in the right frame of mind to play, but is set to make his comeback on the international stage after being included in a 36-man squad on Sunday.
Slipper will continue to skipper Australia, while the uncapped Jock Campbell, Ben Donaldson, Langi Gleeson, Mark Nawaqanitawase, Sam Talakai have been included.
Overseas-based duo Bernard Foley and Will Skelton were also selected for a tour that starts with a Test against Scotland at Murrayfield on October 30.
The Wallabies, who finished third in the Rugby Championship, will also face France, Italy, Ireland and Wales next month.
Australia head coach Dave Rennie said: "We've got a massive opportunity over the next five matches to test ourselves against some of the best teams in the world and string together some performances that our supporters are proud of back home in Australia.
"It's been really pleasing to continue to get game time into our players through the Australia A programme and a number of those guys have been rewarded for their form with selection in the squad.
"To have Michael back in the group is massive for our team on and off the field and we'll continue to make sure that he has the support around him he needs."
