Wallabies coach Dave Rennie has confirmed Lalakai Foketi will start for the second Test against Argentina in San Juan on August 14.
Foketi moves into inside centre for his maiden start in place of Hunter Paisami.
Foketi made his debut for the Wallabies on the Spring Tour against Wales, partnering Len Ikitau, and will match his Waratahs teammate Jed Holloway for Test caps with two after Jed was named in the team after an impressive first showing.
He is joined by Lalakai Foketi, with the Waratah slotting into inside centre for his maiden start in place of Hunter Paisami (concussion).
James O’Connor will start at flyhalf, coming into the side after a season-ending injury to Quade Cooper during last week's 41-26 victory.
Rory Arnold has overcome a calf injury as he returns to the Wallabies line-up for the first time in 2022.
Arnold will partner Darcy Swain in the second-row, with Nick Frost retaining his spot on the bench.
“After a tough, physical game last week it's great to be able to call on the experience of guys like James and Rory and also see the team's excitement for La and Irae who get to wear the Wallaby gold again on Saturday," Rennie said in a statement.
"It's going to be a proud occasion for Pone and his family and it's a testament to him for the hard work and obstacles he's had to overcome to earn his first Test cap."
Taniela Tupou makes his return to the starting side after Allan Alaalatoa (personal reasons) departed camp to return to Australia.
Alaalalatoa’s absence paves the way for Rebels prop Pone Fa’amausili to make a long-awaited debut from the bench, joined by club teammate Matt Gibbon and Lachlan Lonergan.
They are joined by centre Irae Simone, who is in line to appear in his first Test since 2020
Simone rounds out the bench alongside Reece Hodge and the returning Tate McDermott as the Wallabies look to maintain top spot on the Rugby Championship ladder.
"Argentina and their supporters will be expecting a response this weekend and we'll need to increase our physicality and accuracy to get another positive result in San Juan," Rennie added.
