Craig Parry is savouring the most satisfying victory of his golfing career.

The 41-year-old finally won the Australian Open at his 24th attempt, completing his set of Australia's leading professional titles.

Parry fired a nerveless three-under-par closing round of 69 to finish on 11-under at The Australian GC, one shot ahead of West Australian Nick O'Hern (70), young Sydneysider Won Joon Lee (66) and American Brandt Snedeker (69).

He rates the win more highly than any of his 21 other tournament victories in a professional career spanning 22 years.

"It's amazing. Who would think at 41 I'd win an Aussie Open?" Parry asked after accepting the Stonehaven Cup from 86-year-old Kel Nagle.

"This is the best one ever."

The victory also put him on top of the Australasian order of merit, earning him an automatic start in the British Open next year.

The huge-hitting Lee confirmed he is a star in the making with a scintillating final round, while the consistent O'Hern added yet another near miss to his resume.

Snedeker, who was named on the eve of the tournament as US PGA Tour rookie of the year, enhanced his growing reputation with a tremendous performance on a style of course completely foreign to him.

He called a penalty on himself when his ball moved slightly while he was removing a leaf five holes from the finish.

The penalty stroke ended up being the difference between his score and Parry's.
