A smattering of showers have failed to halt the action at the $2 million Perth International, with two players recording hole-in-ones on Saturday.
Overnight leader Peter Hedblom, who needs to win the tournament in order to keep his European Tour card, has been joined at the top of the leaderboard at six-under by JB Hansen.
Defending champion Bo van Pelt and Australian Brett Rumford are among a group of five players at five-under, but world No.21 Dustin Johnson is seven shots off the leaders and struggling to mount a charge.
Rohan Blizard was singing in the rain after snaring a hole-in-one at the par-three 17th.
But David McKenzie had even more reason to celebrate after his hole-in-one on the par-three eighth won him a car.
McKenzie sits at three-under, while Blizard is struggling at two-over.
England’s 12-time European Tour winner Paul Casey missed the cut on Friday after finishing at three-over from his two rounds.
