A birdie on the final hole saw Christel Boeljon claim victory by one shot at the Australian Ladies Masters at Royal Pines.

Boeljon completed her final round in 68, four under par, to edge out overnight leader Ryu So-yeon along with Kim Ha-neul and Diana Luna who both moved into a tie for second place.

Ryu had a three-stroke lead at the start of the day, but could do no better than a par 72 on the final day, barely comparable to the stunning 11-under round of 61 on Friday that had catapulted her to the top of the leaderboard.

That allowed Luna and Kim to grab a share of second with rounds of 67.

The quartet had been tied on 20-under par when Boeljon and Ryu reached the 18th green.

Luna completed the back nine in just 31 while Kim also finished in impressive form.
