Australia vs England Live : Allan Ala’alatoa, Michael Hooper, Will Genia, Christian Lealiifano also return to the starting line-up after Australia beat Georgia 27-8 in their final pool game.
Petaia has played just two Tests, both on the wing, but Wallabies selectors have backed him to make an impact at outside centre, where he has played for Super Rugby side Queensland Reds.
Meanwhile, England coach Eddie Jones insisted fly-half George Ford has a “significant role to play” on Thursday after he dropped him to the bench for Saturday’s World Cup quarter-final against Australia.
Ford has been one of England’s leading players in Japan but Jones moved captain Owen Farrell from inside centre to fly-half, with Henry Slade given his first start of the tournament alongside Manu Tuilagi in midfield.
Jones, however, insisted Ford would still play a major part in Saturday’s crunch clash between the old rivals in Oita.
“George is in the 23, we have a starting team and a finishing team,” he told reporters at England’s hotel in Beppu on Thursday.
“I spoke to him this morning and he’s obviously disappointed, but everyone has a role in the team.
England XV: Elliot Daly; Anthony Watson, Henry Slade, Manu Tuilagi, Jonny May; Owen Farrell (capt), Ben Youngs; Billy Vunipola, Sam Underhill, Tom Curry; Courtney Lawes, Maro Itoje; Kyle Sinckler, Jamie George, Mako Vunipola
