Ross Ford will make his 100th appearance for Scotland when Vern Cotter's side take on Australia at Murrayfield on Saturday.
The Edinburgh hooker made his debut against the same opponents 12 years ago and this weekend will mark his 84th start for his country.
Ford joins Chris Paterson and Sean Lamont as Scotland's only centurions.
Cotter's starting XV also includes Ford's club-mate Allan Dell, who will make his international debut, while fellow forward Zander Fagerson will enjoy his second outing for Scotland.
"Congratulations first to Ross Ford on reaching this special milestone," said Cotter. "It's fantastic for him and his family that he'll achieve it in front of the home fans at Murrayfield, who I'm sure will give him a great reception.
"To play 100 Test matches for your country is an incredible achievement, with his lasting dedication keeping him among the best hookers in the world for a decade.
"He is a consummate professional and, at 32, he has plenty left to give in a Scotland jersey."
Scotland suffered a gut-wrenching Rugby World Cup quarter-final loss to Australia last year, when a controversial last-gasp penalty saw the Wallabies edge a thrilling match 35-34.
