Western Force coach Simon Cron named six current Wallabies Thursday in his starting side to face the British and Irish Lions, but in a setback, veteran Kurtley Beale was ruled out with a hamstring injury.
The tourists open their nine-game Australian itinerary in Perth on Saturday, desperate to make a winning start after a shock 28-24 loss to Argentina in a warm-up in Dublin last week.
They will face a side skippered by experienced scrum-half Nic White, who along with Nick Champion de Crespigny, Dylan Pietsch, Tom Robertson and Darcy Swain were all released from Australia's training camp in Sydney.
Team-mates Carlo Tizzano, Jeremy Williams and Harry Potter were not and will miss the game.
Beale, a 95-test veteran, was set to play but picked up a hamstring niggle in training on Tuesday.
To compensate, Australia coach Joe Schmidt has allowed Wallabies playmaker Ben Donaldson to make a late dash to Perth.
White partners Alex Harford in the halves with Pietsch and Mac Grealy on the wings and Matt Proctor forming a midfield with Hamish Stewart. Donaldson will start at full-back.
Robertson will line up in the front row alongside Brandon Paenga-Amosa and retiring prop Ollie Hoskins.
Sam Carter will play his final game in Force colours partnering Swain, who last week earned his first Wallabies call-up since 2022, in the locks.
Will Harris, Champion de Crespigny and Vaiolini make up the back row.
The Force have played the Lions once before, losing 69-17 in 2013.
