Full-strength England recall Farrell for clash with WallabiesSports | Nov 17, 2017
Farrell was rested for last weekend's 21-8 win over Argentina at Twickenham in England's opening November rugby international.
But the playmaker is back at inside center for the visit of the Wallabies as coach Eddie Jones seeks a fifth straight win over his native Australia since taking charge of England.
Elsewhere, Mike Brown's failure to recover from the concussion he suffered against the Pumas sees Anthony Watson move across to full-back from wing, with Watson's spot out wide taken by Jonny May, now fit following a hamstring strain.
In the pack, Joe Launchbury was selected at lock alongside Courtney Lawes after George Kruis was dropped.
Powerhouse forward Maro Itoje, who like fellow British and Irish Lion Farrell was rested against Argentina, is on the bench.
"I have selected the strongest 23 to play Australia and we will have to be effective in everything we do this weekend to win," said Jones.
Australia coach Michael Cheika, meanwhile, retained the starting XV that beat Wales 29-21 in Cardiff last weekend. Flanker Michael Hooper will captain the Wallabies, with prop Sekope Kepu set to win his 90th cap.
