Wade Ormsby will take a narrow one-shot lead into the final round of the Fiji International after a late triple bogey saw Jason Norris fall off the top of the leaderboard.
Ormsby produced a brilliant 66 on Saturday, firing seven birdies in ten holes from the eighth to get to ten under par.
And when halfway co-leader Norris carded a triple-bogey seven at the 16th, Ormsby found himself in possession of the outright lead.
Norris is alone in second place after he bounced back with a birdie at the long 17th to get to nine under, with James Marchesani another stroke back in third.
Ormsby began the day three shots off the lead and fell even further back when he carded a bogey at the fifth.
But the 37 year old recovered in style, reeling off four straight birdies from the eighth before making further gains at the 13th and 15th to move into contention.
A birdie at the par-five 17th took Ormsby to ten under and, with Norris dropping three shots at the 16th, he moved to the top of the pile.
Ormsby said: "It was a bit of a surprise coming up the last, I hadn't seen too many leaderboards for the day but obviously I'm very happy with it.
"I didn't think I would be in that position after seven holes, I was getting a bit frustrated. The putter started to get a bit hot so I started to move in the right direction.
"I think everyone who has played golf knows that when the putts start dropping you get happier out there. I had Richard on my bag and he was just saying to try and stay cool, so that happened and I made a tonne of birdies.
"I feel like I am playing quite solid. I haven't made many bogeys for the week and once I got my putter going I really started moving forward.
"I feel like I can keep doing what I am doing, it will just be if other guys get going as well and chase me."
Norris, who began the day in a four-way tie for the lead, opened his round with seven straight pars before firing back-to-back birdies at the eighth and ninth to move to nine under.
Further gains at the 12th and 14th gave Norris a two-shot lead before a triple bogey at the 16th saw him slip into a tie for second.
But he recovered from that setback with a gain at the 17th to reduce Ormsby's lead to a single shot.
Norris was pleased to get a shot back so soon after the triple bogey. He said: "It's a tough tee shot - I hit a poor drive. I don't mind that hole, I drive there all the time, and in the hazard you should still make five but a couple more poor shots as well and it adds up to a seven.
"It's always good to play an easier hole after a bad hole and hopefully make a good birdie coming back so it was good to come back that way. I was actually thinking when I hit that shot in it was going to be an eagle. I saw it bounce but didn't see it roll in, you can't see it from back there and I thought it was going to be pretty close."
"I could have easily made a double but got away with a five and then just sort of stayed patient, which is pretty easy to do just looking at that water out there. I then managed to make six birdies on the back."
