Ian Poulter failed to retain the Australian Masters title as Adam Scott pulled clear to notch a four-shot victory at Melbourne's Kingston Heath Golf Club.
The tournament had turned into a final-round showdown between the pair after they had put daylight between themselves and the rest of the field on Saturday.
Englishman Poulter started the day one ahead but local favourite Scott had edged in front by the turn after five birdies on the front nine, with only one blemish, a bogey at the fourth.
Poulter made a steady start with a bogey on the fifth sandwiched by birdies at the third, seventh and eighth.
However, he made a hash of the par-fives on the back nine, with bogeys at both the 12th and 14th, to hand Scott a clear advantage.
A birdie at the 16th stopped the rot but he then missed a one-foot par putt on 17 to gift Scott the title which he wrapped up with a birdie on the 18th.
World No 5 Scott finished with a five-under 67 for a 17-under total of 271, while Poulter signed for a level-par 72.
New Zealand duo Gareth Paddison (68) and Mark Brown (69) tied for third on nine under and Northern Ireland's Graeme McDowell finished in a tie for eighth on two under after closing with a 71.
