Adam Scott remains in the hunt for a third successive Australian Masters title but will have to come from four shots behind on the final day.
Scott is attempting to become the first player to win the tournament three years in a row and, after a one-over-par 73 in his first round, he shot a four-under-par 68 on Friday and a one-under-par 71 on Saturday to stay in the reckoning.

The world No 2 is one of eight players four shots off the pace, with Paul Spargo taking full advantage of Michael Wright's disappointing two-over-par 74 to take the lead on eight under.
Wright had led for the first two rounds at the Metropolitan Golf Club but now trails Spargo by a shot after he recorded five bogeys on Saturday.
Lucas Herbert, Nick Cullen and James Nitties are a further shot back on six under, while Geoff Ogilvy and Josh Younger are three shots off the lead on five under.
Chris Campbell, Nick O'Hern, Adam Bland, Nick Felton, Aaron Price, Matthew Griffin and Matthew Guyatt are the other seven players to join Scott on four under.
Scott admitted after his round that he needs a fast start on Sunday.
"Anyone sitting in my position tomorrow is going out with no pressure," Scott said.
"If I can get off to a fast start and somehow be within a couple of the lead when I'm turning and they're teeing off five or six holes behind...
"Posting a (low) number is a big thing in a golf tournament with some tough finishing holes here. It makes them think and thinking can be dangerous in golf.
"I need to get bolder. I've been a little cautious but I can't afford to be tomorrow."
The 34-year-old Spargo, who is world ranked 1126, is excited by the challenge leading an event of this stature poses.
"The more you put yourself up there in contention and playing with the leaders you get used to it so all the experience will definitely help," Spargo said.
"I've come a long way in a couple of years and my game's been good so I've done my time and this is the next step."
