Will Skelton, Rory Arnold and Tolu Latu have been recalled to the Australia squad for their upcoming tour of the northern hemisphere.
The France-based trio was on Friday named in a 37-man party to face Japan at Oita Stadium on 23 October before travelling to Europe to take on Scotland, England and Wales next month.
Skelton has not played for the Wallabies since 2016, but the towering La Rochelle lock is set to add to his 18 caps.
Fellow second-row forward Arnold, who plies his trade with Toulouse in Top 14, and Stade Francais hooker Latu have not played for their country since the 2019 Rugby World Cup in Japan.
Lalakai Foketi, Izaia Perese, Pone Fa'amausili and Connal McInerney are the uncapped quartet in the squad.
Japan-based players Quade Cooper, Sean McMahon and Samu Kerevi, who has recovered from an ankle injury, were included on the back of Australia's second-placed finish behind New Zealand in the Rugby Championship.
Dave Rennie's side has won four consecutive games, seeing off world champion South Africa and Argentina twice.
Head coach Rennie said: "Firstly we're extremely grateful to be able to represent Australia on the world stage in the current environment and that's something that's not lost on this group.
"We've been building as a squad over the past 18 months or so and to get a chance to head to the northern hemisphere and test ourselves against four really strong International sides is a great opportunity to learn more about ourselves."
