The Wallabies have rushed back Will Genia to face Scotland, but opted against doing the same to the suspended Dean Mumm - with Michael Cheika sticking with the back-row that shut out Wales.
Genia, who was withheld by his French club Stade Francais for last week's outside-the-international-window clash, reclaims the No.9 jersey he starred in throughout the Rugby Championship.
In the only change to the starting line-up from the team which thrashed Wales 32-8 to kick off a grand slam bid, accomplished halfback Nick Phipps has been relegated to the bench meaning Nick Frisby drops out of the match-day squad altogether.
In a shake up to the bench, Cheika also recalled rookie prop Tom Robertson in place of the experienced James Slipper and giant lock Will Skelton for Scott Fardy, while Mumm comes in at the expense of outside back Sefa Naivalu.
Influential backrower David Pocock, on light training duties early in the week as he recovers from a concussion suffered on Saturday, has been retained at blindside flanker, with vice-captain Michael Hooper and No.8 Lopeti Timani completing the Wallaby back-row.
That leaves no room in the starting lineup for the experienced Mumm, whose one-game suspension for striking forced Cheika into deploying the makeshift trio against Wales.
It proved mightily effective, with Australia dominating across the park with Pocock on the field - both at the breakdown, but also in the set piece where the 28-year-old's smaller frame was meant to have hurt the lineout effectiveness.
Cheika indicated Mumm play a crucial second-half role, but said Timani's hot form was making him impossible to drop.
"He's continually making me pick him. That's the issue - his performances have spoken for themselves," Cheika said.
"He's been consistent and that's all we can ask of the guy. He's doing lots of good tight work and also when he needs to carry he's carrying well.
"So I'd like to let him have an opportunity to run this form out and learn how to back up and play week to week in that atmosphere."
Cheika also admitted Phipps had made life difficult at the selection table by lifting his standard of play with crisp displays against the All Blacks and Wales, but ultimately hadn't done enough to dislodge the classy Genia.
"I think Phipps had two really good games, I do, but I thought (Genia) has been one of our best all season," Cheika added.
"I just feel that this is a good game for him to play, come back in and get straight into it and then Nick will finish the game.
"I think Nick's standard has definitely gone up from what I saw earlier in the year and now there's a real competition going on there."
