Ireland's coach Declan Kidney has made four changes to the team to play Australia in Auckland on Saturday night.
Fullback Rob Kearney, flanker Sean O'Brien and prop Cian Healy return after recovering from injury while first-choice halfback Eoin Reddan will start, with Conor Murray moving to the bench.
Kearney replaces Geordan Murphy in the team that beat the United States 22-10 on Sunday, with O'Brien taking over from Shane Jennings.
Saturday's match will be Ireland's second appearance in the Rugby World Cup.
Australia lead Pool C after their bonus point victory over Italy on Sunday with Ireland one back on four points.
