Wallabies coach Robbie Deans has named 15 Reds players in his 40-man Tri-Nations squad.
Veteran Radike Samo, 35, earns a call-up after an impressive season, while reserve hooker James Hanson was the bolter in the group.
Injury plagued Rocky Elsom retains the captaincy despite playing only one Super Rugby match this season, while Phil Waugh and Stirling Mortlock failed to make the cut.
Daniel Vickerman is included as expected. The lock hasn’t played Test rugby for three seasons while he completed his studies, but Deans is known to be an admirer.
Waratahs backs Drew Mitchell, Rob Horne and Berrick Barnes, and Force No.8 Richard Brown were all left out due to injuries but Deans said they still remained in World Cup contention.
The Wallabies will announce their 30-man World Cup squad on 18 August.
