South Korea's Lee Chang-Hee holds a two-stroke lead at the halfway point of the 2009 Australian Open at Melbourne's Metropolitan Golf Club.
The 20-year-old backed up her opening round 69 with a 70 today to displace defending champion Karrie Webb from the top of the leaderboard.
At five-under, Webb has a share of second place with England's Georgina Simpson, who hit a 68 - the best round of the day, and Tania Elosegui of Spain who fired a 72.
Katherine Hull finished at plus-four, the same as playing partner Laura Davies who was livid with herself for finishing with three successive bogeys for a 76.
Twelve-year-old Melbourne schoolgirl Oh Su-Hyun, the youngest-ever player to compete in an Australian Women's Open, failed to make the cut.
Much as she did on Thursday, Oh faded over the closing stages of her round to finish with an 81, plus-14 overall.
