Robbie Deans' backline dilemma has not been made any easier by Quade Cooper's knee injury, with a tough choice pending between Berrick Barnes and Kurtley Beale as Wallabies five-eighths.
Both Barnes and Beale are certain to line up against South Africa next week in Pretoria now Cooper is sidelined, but coach Deans is considering starting each away from their regular positions.
Building the intrigue, the playmaking selection is expected to reflect the style of play Australia aim to use to continue their recent dominance over the Springboks, winning seven of their past eight contests.
Renowned for his reliability, Barnes has better kicking skills more suited for a conservative field-position game while Beale is an explosive ball-running No10.
Barnes has often lined up at five-eighths for either the Waratahs or Wallabies with Beale his go-to man at fullback.
