Mitchell bagged a hat-trick as Australia humiliated France. The tourists ran riot in the second half, scoring six tries in 31 minutes to embarrass the reigning Six Nations champions in front of their own fans.
Les Bleus had led 16-13 at the start of the second period, courtesy of Morgan Parra’s third penalty.
But the hosts had no answer to the Wallabies’ devastating second-half surge, scoring seven tries in total.
After Adam Ashley-Cooper’s early score, the visitors’ problems at the scrum were exposed when France were awarded a penalty try and duly moved into a 16-13 lead.
