Stephen Moore and Matt Giteau will become the seventh and eighth Wallabies to reach a century of test caps for Australia when they start in the team's RWC quarterfinal match‑up with Scotland.
Teammate Adam Ashley‑Cooper will make a 112th test appearance.
Head coach Michael Cheika has made four changes to the starting line‑up with Rob Simmons, Michael Hooper and Ben McCalman all returning to the side.
In the backs, Kurtley Beale makes his second start in the tournament, replacing Israel Folau at full‑back.
Cheika said the 100 caps for Giteau and Moore were significant milestones but the best thing the side could do to honour the veterans would be to qualify for a World Cup semifinal.
The Wallabies will take on Scotland at 3am Monday while Ireland will take on Argentina at 12am.
In tomorrow’s matches, New Zealand will meet France at 7am while South Africa will take on Wales at 3am.
