Georgia coach Levan Maisashvili has brought Beka Gorgadze into a rejigged back row for his side's World Cup pool C opener against Australia at the Stade de France.
Gorgadze emerged as his country's top No.8 at the last World Cup in Japan and returns to the back of the scrum for Saturday's (Sunday AEST) clash in Paris after missing the last warm-up match against Scotland because of injury.
Tornike Jalaghonia moves to blindside flanker to make way for Gorgadze, while young gun Luka Ivanishvili shifts to the openside flank.
Maisashvili said injured Lyon loose forward Beka Saghinadze was training but not yet ready to play, although he did expect him to be fit to face Portugal in Georgia's second pool match on September 23.
"This is the World Cup and in every match we will have the best squad for the given moment," the coach said. "The coaches considered these 23 players are the best prepared for this moment."
Maisashvili has kept his backline intact from the 33-6 loss to Scotland with skipper Merab Sharikadze and Demur Tapladze in the centres and standout Davit Niniashvili at fullback.
Twelve of the matchday squad play their club rugby in France and nine played in the pool fixture against Australia at the 2019 World Cup, which Georgia lost 27-8.
They will be looking for a better result on Saturday after wins over Italy and Wales in the last year proved that they can beat top-tier teams.
"We have analysed Australia's game and we know what we have to face. Everything will depend on how well we can play our game and take our opportunities," Maisashvili said.
"I think that the team is physically well prepared. We saw against Scotland that we didn't have any problems with physicality.
"We have nothing to lose against Australia and we will fight until the end."
Winners of the last five second-tier Rugby Europe Championships, Georgia are ranked 11th in the world, only two places below the twice world champion Wallabies.
