Rising backrow star Isi Naisarani has been unveiled as the final piece of the Wallabies' Spring Tour puzzle, named as a squad development player.
Naisarani has been training as an unofficial member of the squad in Japan and his efforts have impressed the coaching staff enough to earn a spot alongside fellow development rookie Rob Valetini in the squad.
Hooker Tatafu Polota-Nau is the other addition to the squad once they land in the UK, with Wallabies coach Michael Cheika giving the rake some time off in England while the squad trained in Japan.
Brandon Paenga-Amosa and Jed Holloway are both returning to Australia after training and playing with the squad in recent weeks.
Holloway has battled niggles since joining the squad in Sydney and will be released from the group to recover.
Lock Adam Coleman is expected to be fit for the Wallabies' first Test in the UK after missing the third Bledisloe Test with a groin injury.
Coleman has trained fully during Australia's extra week in Japan, a positive sign ahead of their European tour.
The Wallabies flew to Wales on Saturday ahead of their November 11 Test in Cardiff.
Australia takes on Wales on Saturday November 10, kicking off at 5:20pm local, Sunday 4:20am AEDT, LIVE on beIN Sports and SBS.
