Greg Chalmers held on to win his second Australian Open at the Lakes Golf Club in Sydney on Sunday.
Chalmers, 38, scored a three-under-par 69 for 13-under overall, making two birdies on the back nine after a strong start to secure a one-shot win over fellow Australian and 2006 champion John Senden.
Tiger Woods fired a five-under 67, but finished two strokes behind the eventual winner after falling six shots behind in the previous round.
Chalmers becomes the first left-hander to lift the Stonehaven Cup since he last won in Adelaide in 1998.
