Mark Nawaqanitawase almost single-handedly saved the Wallabies' blushes against Wales last year with the young winger now set to play a key role in saving Australia's World Cup campaign.
The desperate Wallabies' quarter-final hopes go on the line against Wales in Lyon on Sunday (Monday AEST) with a defeat guaranteed to send them packing at the pool stage for the first time.
While the Australians suffered a shock loss to Fiji last round, pool leaders Wales are unbeaten through their two games and are relishing the chance to lock up a final-eight spot with a match to spare.
