Sussex's Billy Twelvetrees will replace Owen Farrell at inside centre for England's international against Australia at Twickenham on Saturday.

Farrell has been overlooked for the starting XV for the first time since June 2012 after under-performing against New Zealand, South Africa and Samoa and is demoted to the bench.

The experiment of playing the 23-year-old at 12 has been abandoned after only one match with Twelvetrees, who comes from Pulborough, chosen to line up outside fly-half George Ford after impressing as a second-half replacement in the 28-9 victory over Samoa.

Ford produced an accomplished full debut against the Pacific islanders and it is hoped the presence of a more genuine inside centre than Farrell will help ignite the attacking game that has spluttered throughout the autumn.

''It's good to be able to give Billy his first start of the series,'' head coach Stuart Lancaster said.

''He took on board the feedback we gave him when he first came into camp and he has worked hard both with us and at Gloucester. He deserves his chance.

''Owen is a key part of our squad and I'm sure he'll make a positive contribution should he get the chance.''

Two further changes have been made to the starting XV that dispatched Samoa with Northampton forwards Dylan Hartley and Tom Wood restored to the pack.

Hartley replaces Rob Webber at hooker after being punished by Lancaster with demotion to the bench for receiving a brainless yellow card against the Springboks and Wood swaps places with James Haskell at blindside flanker.

Joe Marler, from Eastbourne, retains his place in the team.
