England's uncapped youngsters
Props Ellis Genge, of Bristol, and Harlequins' Kyle Sinckler have been included in Jones' squad, along with Northampton back row Teimana Harrison.
Jones says both of the uncapped props have a "competitive edge".
He added: "Both aren't ready to scrummage at Test level but both have got potential, so we need to bring them through.
"Genge is a boy that's not afraid of anything and that's what we need to beat Australia. He's aggressive and he can run with the ball and he's got that bit of an edge about him."
The former Australia and Japan head coach continued: "Harrison has been absolutely outstanding for the Saints.
"The robustness of his play, his physicality and his ball carries, his low tackling and his coachability make him a great player to add to the squad.
"He's got a hard back row to break in to. Robbo [Chris Robshaw], James Haskell and Billy [Vunipola] obviously did well during the Six Nations and there's no reason they can't continue to play well."
