Jonathan Joseph will return from injury to start in the midfield for England against the Wallabies on Saturday.
England delayed naming the team until midday on Thursday to give the players a chance to come through their final training session unscathed, with Joseph proving his fitness in order to reclaim the No 13 jersey as Brad Barritt reverts to inside centre.
Ben Youngs was another injury-doubtful after picking up an ankle injury, but he has also been passed fit, while Ben Morgan returns at No 8 as replacement for the injured Billy Vunipola. Joe Launchbury will start in the second row alongside Geoff Parling, with Courtney Lawes ruled out.
'JJ [Joseph] and Ben Youngs are both fit and raring to go, as are the rest of the squad for what will be a huge game against a very good team,' coach Stuart Lancaster said. 'England-Australia matches at Twickenham are always massive occasions, this one more than ever, and we want everyone behind us so we can get the result we all want.'
