Tigers star Geordan Murphy is back in the Ireland side to face Australia in Dublin this Sunday. Murphy starts at full back against the Wallabies, having been named on the bench for last weekend's clash with South Africa.

Murphy will win his 44th cap after being given 23 minutes of action as a second half replacement during last Saturday's 32-15 win over the Springboks.

The Leicester man is one of four changes for the Irish, with Denis Hickie earning a spot on the wing and Ulster pair Issac Boss and Bryan Young gaining their first international starts.
