Sione Tuipulotu will once again captain the squad from inside centre, having scored against the Wallabies on their most recent visit to Edinburgh back in November 2024.
He will be assisted by two of his Glasgow Warriors team-mates, after Kyle Steyn and Rory Darge were both named as vice-captains for Sunday’s clash.
Zander Fagerson is once again the most-capped Warrior selected in the matchday 23, the tight-head prop set to win his 86th cap for his country.
Rory Sutherland joins Fagerson in the front row, with an all-Glasgow second row combination of Gregor Brown and Scott Cummings selected for the second successive fixture.
Matt Fagerson joins Darge in the back row, lining up on the blindside flank for this weekend’s match.
Three further Warriors are selected amongst the replacements; Gregor Hiddleston and Max Williamson provide cover at hooker and second row respectively, whilst Jamie Dobie rotates to the bench in a six-two split of forwards and backs.
Scotland face Australia at Scottish Gas Murrayfield this Sunday, with kick-off scheduled for 3.10pm.
