Matthew Stieger carded a 4- under 68 on Sunday to earn his first professional win at the New South Wales PGA Championship.

Stieger finished the event at 15-under 273 -- three shots ahead of Daniel Nisbet, who carded a 69 in the final round at Mt. Broughton Golf and Country Club in the Southern Highlands.

With the win, Stieger -- a tour rookie -- secured a spot in next week's Australian Open.

Nick Cullen shot 67 on Sunday and ended alone in third place at 5-under, while Ryan Fox (70) and Kyle Grant (68) tied for fourth at minus-10.
