Sydney - Halfback Nick Phipps and blindside flank Lukhan Tui will start for Australia in the Wallabies' series-deciding Test against Ireland on Saturday.
Rugby Australia said Thursday that 63-Test veteran Phipps would replace the injured Will Genia, while Tui's promotion forced David Pocock to move to No 8 where he will replace the dropped Caleb Timu.
They were the only changes to the starting lineup made by coach Michael Cheika.
Genia sustained a broken right arm in the second Test won 26-21 by Ireland in Melbourne. Australia won the first test 18-9 in Brisbane.
Joe Powell could add to his three Test caps after being named on the bench as reserve halfback, along with 2017 Wallabies rookie of the year Ned Hanigan, who returns from a knee injury.
Ireland made several changes, including in the frontrow where Jack McGrath and Sean Cronin will partner Tadhg Furlong. In the second row, James Ryan and Devin Toner pack down again while the back row has a new look with Jack Conan coming in at Number 8, CJ Stander switches to 6 and Peter O'Mahony moves to No 7.
The halfbacks pairing of Conor Murray and Johnny Sexton will be joined in midfield by Bundee Aki and Robbie Henshaw. Jacob Stockdale returns to the back three alongside Keith Earls and Rob Kearney.
The uncapped Ross Byrne was named in the reserves, as was Tadhg Beirne, who made his debut last week in Melbourne.
Australia and Ireland last played in Sydney in 1994, when the Wallabies won 32-18 at the Sydney Cricket Ground. Saturday's decider will be played at the 45 000-seat Sydney Football Stadium, and Rugby Australia said the match is a sellout.
