Also back in favour is Ulster hooker Rory Best who replaces Jerry Flannery with coach Michael Bradley making two changes from the side that started against the All Blacks in Wellington. The Shannon and Munster scrum-half has been out of favour with the national side since the World Cup and he now gets his chance to prove that he is still worthy of the number one spot on the national side. Stringer will be winning his 84th cap, extending his record as the most capped Irish scrum-half of all time.
Luke Fitzgerald and Alan Quinlan are both ruled out with injuries while Jerry Flannery and Eoin Reddan are on the bench. Australia are expected to name their side later today.
Ireland: Rob Kearney; Shane Horgan, Brian O'Driscoll, Paddy Wallace, Tommy Bowe; Ronan O'Gara, Peter Stringer; Marcus Horan, Rory Best, John Hayes; Donncha O'Callaghan, Paul O'Connell; Denis Leamy, David Wallace, Jamie Heaslip. Replacements: Jerry Flannery, Tony Buckley, Mick O'Driscoll, Shane Jennings, Eoin Reddan, Geordan Murphy, Girvan Dempsey.
The game kicks-off at 11.05am Irish time and is being shown live on Sky Sports.
