England's Ian Poulter won the JBWere Australian Masters on Sunday, spoiling Geoff Ogilvy's bid for a victory on his boyhood course.
Poulter, two strokes behind Ogilvy entering the final round, closed with a 4-under 67 in windy conditions to finish at 15-under 269 at Victoria Golf Club.
Greg Norman won the JBWere Australian Masters six times between 1981 and 1990.
Australian Marcus Fraser had a 64 to finish second, three strokes back. Ogilvy, the 2006 U.S. Open champion who matched the course record with a 63 on Saturday, shot a 73 to end up third at 11 under.
Poulter quickly erased Ogilvy's overnight lead with an eagle-2 on the opening hole. He then made a birdie on the seventh to take the outright lead and added another on the ninth to make the turn with a two-shot advantage.
"To come down here the week before Christmas and to win this tournament is very special," he said. "I had a message from (former champion) Justin Rose who said, 'Put a nice gold jacket in your wardrobe like I have,' and it's nice to do that."
World No. 1 Luke Donald had four birdies on the front nine to move up to fifth place, but followed with four bogeys on the back nine to finish with a 1-over 72 and a share of 12th.
Greg Chalmers failed in his bid to become the second player to complete the Australian Triple Crown, shooting a 74 to join Donald in the group at 4 under. Robert Allenby remains the only player to sweep the Australian Open, Australian PGA Championship and Australian Masters in the same season. He accomplished the feat in 2005.
Poulter putted well in the final round, despite the windy conditions.
After sticking his opening tee shot 15 feet beyond the pin on the short par-4 first, he sent his putt straight into the hole for eagle. He then sank a long putt to save par on the fifth and putted across the green for birdie on the seventh.
He nearly made another eagle on the ninth, with the ball stopping just inches from the hole.
"After the first couple of days when there wasn't much wind, people may have thought the Victoria Golf Club was easy, but they were mistaken," Poulter said. "It certainly showed its teeth today."
Ogilvy showed signs of life on the back nine, sinking a long putt for birdie on the 16th, but Poulter matched his birdie to maintain his three-shot lead. A bogey on the 17th was the only blemish on Poulter's final-round scorecard.
Fraser had eight birdies and a bogey to surge past Ogilvy for second. Ogilvy, who grew up playing at Victoria Golf Club, had two birdies, two bogeys and a double bogey in his final round.
Australian veteran Peter Senior finished in a share of fourth place with compatriot Adam Crawford.
