Cheika recalls big guns for Ireland
Fullback Israel Folau and No.8 Michael Hooper headline six players who are back in the starting XV after sitting out last weekend's 25-23 win over France in Paris.
Stephen Moore, who grew up in Ireland before moving to Australia as a young child, returns at hooker to win his 116th cap and join Adam Ashley-Cooper and Nathan Sharpe as the equal second most-capped Wallabies players in history.
Dean Mumm will start at blindside flank in a reshuffle of the back row with Lopeti Timani named on an extended bench alongside fellow Melbourne Rebels teammate Sean McMahon.
Quade Cooper was also named on the bench after being ruled out prior to kick-off against France last Saturday because of an ankle injury.
The Wallabies are chasing their fourth-straight Test victory, in what would be their best winning sequence since notching seven consecutive wins on their run to the 2015 World Cup Final.
A victory in Ireland would set Australia up for a first tilt at a Grand Slam of the Home Nations since 1984, with a tour-ending match against Eddie Jones' England slated for December 3.
