Australia ended their run of seven straight defeats with a deserved win over a lacklustre Ireland in Dublin.
Ireland (6) 14
Pens: O'Gara 2, Humphreys
Australia (3) 30
Tries: Mitchell 2, Latham
Cons: Rogers 3
Pens: Rogers 3
Trailing 6-3 at the break after Ronan O'Gara knocked over two penalties for the Irish, the Wallabies stormed back with three second-half tries.
Winger Drew Mitchell touched down twice with full-back Chris Latham scoring a great individual try.
Mat Rogers kicked 15 points while Shane Horgan scored a late try for Ireland, but it was nowhere near enough.
The home side started the more positive however, and deservedly slipped ahead in the seventh minute with O'Gara chipping over the opening penalty.
Ireland almost added to their score in the 18th minute when Johnny O'Connor made a charging break from a midfield ruck but from a resulting penalty O'Gara drifted the ball past the upright.
During the move, Ireland lost their most-capped player when Malcolm O'Kelly suffered a head injury and was stretchered off following a ferocious pincer tackle by Lote Tuqiri and Hugh McMeniman.
Only rarely did Australia threaten, but solid Irish defence easily kept them at bay.
It was a turnover tackle by debutant Andrew Trimble that initiated the move that finally saw O'Gara double his side's lead with a 35m penalty.
Just before the break, wing Tommy Bowe would surely have scored in the left-hand corner only for a poor finishing pass from Geordan Murphy.
Rogers immediately levelled the game on the restart with a simple penalty after Ireland held on in the tackle.
Ireland were further punished in the 45th minute when they failed to take Mitchell out of the game, and as the winger stayed on his feet, his support players pushed him over the line for the try.
Rogers landed the conversion and a game well within Ireland's compass started slowly slipping away from them.
Ireland took off fly-half Ronan O'Gara and introduced David Humphreys into the fray with 30 minutes remaining in the hope of raising the tempo of the game.
Ireland's record points-scorer landed a penalty, but that only signalled Australia's revival.
With Ireland's line-out falling apart, the Wallabies then took charge with first Latham bursting through a gap between Humphreys and O'Connor to steam in under the posts from 50m out.
In attempting to spring Ireland into life, Humphreys saw his pass intercepted and Mitchell took off down-field and although he was initially stopped by Bowe, the winger regained his balance to dive over for his second try.
Ireland grabbed their only try four minutes from the end when Humphreys's sleight of hand made the space for Murphy to put Horgan over.
Australia, though, had the final say when Rogers converted his third penalty to put an end to the seven-game losing streak.
