Adam Scott has teed off in his final round of the Australian PGA Championship at Royal Pines on the Gold Coast.

The world No.3 is chasing back-to-back championships and has started Sunday’s action in a share of the lead with South Australia’s Wade Ormsby and Western Australia’s Scott Strange on 10-under-par.

American Boo Weekley has made par on his first hole and remains one shot behind the leaders on nine-under.

West Australia’s Jason Scrivener, who had started the day one shot off the lead, bogeyed the first and is back to eight-under.

Jun Seok Lee is the big mover so far in the final round, making birdie in four of his first six holes to move to seven-under.

PGA Tour winner John Senden (-4) made a bright start with four birdies in his opening five holes but back-to-back bogeys have halted his charge.
