Rookie scrum-half Teddy Wilson was among two debutants included Friday in the Wallabies squad for the Nations Championship, following in the footsteps of his World Cup-winning father David.
With Australia hosting the World Cup in a year's time, coach Les Kiss has tapped the 23-year-old as back-up to Ryan Lonergan and Tate McDermott.
Wilson's father played 79 times for Australia, nine as captain, and was a member of the 1999 World Cup-winning side.
Joining him in a maiden Australia squad is loosehead prop Tom Lambert.
Australia head to Europe for Tests next month against England, Scotland, Wales and another yet-to-be-determined side in the Nations Championship finals weekend.
They are boosted by the return of Europe-based Taniela Tupou and Tom Hooper, who played crucial bench roles in Australia's defeat of world champions South Africa in Perth last month.
Kiss was then without them for heavy back-to-back Bledisloe Cup defeats to New Zealand, given those Tests fell outside of World Rugby's global player release period.
Fly-halves Carter Gordon and Ben Donaldson and centre Len Ikitau all return from injuries, while Hunter Paisami is back after suspension for a high tackle.
"There's a real buzz among the squad as we prepare for what will be four incredibly demanding matches against high-quality opposition as part of the November Nations Championship Tests," said Kiss.
"As coaches we've made some tough selection calls to keep building depth across the board and we know a tour like this will challenge the whole squad on many levels.
"This tour gives us another valuable opportunity to test new combinations, strengthen our existing connections and push our game forward in all areas."
