Western Force coach Tim Sampson has made minor changes to his side that was beaten by the Waratahs last Friday.
In the back-row, Fergus Lee-Warner gives the Force some extra height at the lineout by shifting from the second-row to blindside flanker for Henry Stowers.
Ollie Atkins has been promoted to the starting side and joins former All Black Jeremy thrush in the second-row.
Up front, former Red Andrew Ready has too been promoted to the starting side and forms a strong front-row alongside Pek Cowan and Kieran Longbottom.
It's an unchanged backline with Sampson hoping that some much needed continuity helps settle the side.
Former captain Heath Tessmann will come off the bench for his first minutes of the season.

The Reds have, too, only made minor changes.
The injury to Hunter Paisami has seen Brad Thorn bring in Josh Flook at outside centre with Jordan Petaia remaining on the right-wing and Jock Campbell in his preferred position at fullback.
It's an unchanged forward pack with Thorn rewarding his big men for their outstanding defensive effort during last weekend's 19-3 win over the Reds.
On the bench, Josh Nasser acts as the reserve hooker while prop Harry Hoopert returns after hi injury absence.
Halfback Moses Sorovi comes on to the bench with Scott Malolua dropping out of the squad.

White's return off the bench is the headline name to return.
But right throughout the side, there's key changes.
Solomone Kata will start at outside centre with Wallaby Tevita Kuridrani out which also sees Tom Wright, fresh from re-signing with the Brumbies, coming on to the left-wing.
Junior Wallabies halfback Ryan Lonergan starts for the absent Joe Powell.
Up front, James Slipper starts ahead of test teammate Scott Sio and Connal McInerney makes a rare start with Folau Fainga'a missing.
Veteran locks Cadeyrn Neville and Murray Douglas return which sees Darcy Swain back to the bench and Nick Frost drop out of the squad.
In the back-row, hard-man Lachie McCaffrey starts ahead of Rob Valetini at blindside flanker.
McKellar has opted for a forwards-heavy six, two bench split.
Waratahs coach Rob Penney has kept faith with the majority of his side too following their 28-8 win over the Force, which saw them record back-to-back wins for the first time since March, 2019.
The only change to the backline sees Joey Walton promoted at outside centre with Lalakai Foketi dropping to the bench.
Up front, there's two changes with Ned Hanigan promoted to the starting side to join captain Rob Simmons in the second-row.
Tight-head prop Harry Johnson-Holmes starts ahead of Tetera Faulkner.
