Windy conditions made the Royal Melbourne Golf Club tougher than usual for the third round and just nine players broke par. Nikki Campbell had a 3-under 70 for the best score of the day.
Korda is at 4-under 215 after 54 holes, one stroke better than Campbell, second-round leader Ryu So-yeon and Seo Hee-kyung. Ryu had six bogeys and three birdies en route to a 76 while Seo turned in a 2-over 75 Saturday.
Even Campbell's round was spotted with back-to-back bogeys at Nos. 9 and 10 against five birdies.
Korda had a bogey at the fifth hole but moved into the lead with three birdies in a four-hole span. She had birdies at 9 and 10 where Campbell was getting bogeys. But Korda returned to the field with bogeys at Nos. 13 and 17.
