Home golfer Daniel Popovic completed his first professional victory after completing a four-shot triumph at the Australian PGA Championship on what was a dramatic final day at the Palmer Coolum Resort.

Popovic began the round two shots ahead and increased his lead after an early birdie before a double bogey on the par three eighth saw him slip a shot behind Rod Pampling.

A birdie on the par five 12th brought him to within a shot of the leader, but Pampling, who began the day with six straight birdies faltered with consecutive bogeys.

A birdie at 17 put Popovic firmly in the driving seat with a two-shot lead and his advantage was increased to four after Pampling double bogeyed after finding the water.

A par at the last confirmed Popovic's victory with the Australian carding a 69 in the final round to finish 16 under par and claim the $225,000 winners cheque.

Pampling finished second on 12 under alongside Anthony Brown, a shot clear of Geoff Ogilvy (69) and Brad Kennedy (70).
