Louis Oosthuizen made his first tournament appearance in Australia a winning one, shooting a 1-under 71 for a one-stroke victory at the Perth International on Sunday.

The former British Open champion, who led by three strokes going into the final round, finished with a 16-under total of 272 in the tournament sanctioned by the European and Australasian PGA tours.

Alexander Levy of France was second after a 66, followed by West Australian golfer Jason Scrivener, whose 69 left him in third place, two strokes behind.

American Peter Uihlein (71) and France's Gregory Bourdy (66) were tied for fourth, three behind Oosthuizen.
