David Pocock will start at openside flank for the Brumbies in Friday's quarter-final against the Highlanders in Canberra.
Pocock has recovered from a fractured eye socket sustained during the Wallabies' first Test against England in June.
However, lock Rory Arnold has been ruled out of the quarter-final after failing to recover from an elbow injury suffered against the Force last week and is replaced by Blake Enever.
In other changes, Robbie Coleman returns after three weeks of strong performances in club rugby to replace James Dargaville on the left wing, while Ruan Smith will start at tighthead prop.
