Louis Oosthuizen held on to his overnight lead to clinch an eighth European Tour title with victory by one stroke in the Perth International on Sunday.
The 2010 Open winner went into the final day at Lake Karrinyup Country Club with a three-shot advantage over the chasing pack.
Oosthuizen did see his lead erased briefly on the front nine, but his one-under-par 71 sent him to 16 under for the tournament and proved enough to hold on and seal his first Tour title since January 2014.
Home hope Jason Scrivener was the man to catch Oosthuizen, whose bogey at the par-four second allowed the Australian to level with birdies at the first, third and seventh.
However, Oosthuizen soon replicated Scrivener's achievement in getting up and down from a bunker on the seventh to go one stroke ahead once more.
An excellent tee shot on the eighth left Oosthuizen with a seven-foot putt for birdie that he duly made to go three shots clear again as Scrivener's par putt on the ninth fell short.
Peter Uihlein cut the gap to two with a gain on the same hole but the American, along with Scrivener and Romain Wattel - who had been within one of Oosthuizen after an eagle on the third - all fell away on the back nine.
A birdie at 12 put Oosthuizen four clear and, although Alexander Levy made gains on five of the last nine holes to trim the gap to two strokes, it was enough for the South African to protect.
Oosthuizen finished with a bogey on the last, ensuring triumph ahead of Levy on 15 under, with Scrivener a shot further back.
Uihlein ended on 13 under along with Gregory Bourdy, while Wattel's level-par 72 saw him close four shots behind champion Oosthuizen.
