Caroline Hedwall of Sweden leads the way at the women's Australian Open after a hole in one at the 16th helped her to card a seven-under-par second round of 65.
Hedwall is 11-under-par at the halfway point after finishing her round in stunning fashion and is a shot clear of Norway's Suzanne Pettersen, while another Swede, Anna Nordqvist, is three shots back after a course record 64.
Having started on the 10th at Victoria Golf Club, Hedwall aced the 16th, but bogeys at three and six dropped her back to three-under for the day.
However, she then conjured up a stunning birdie-eagle-birdie finish to reach the top of the leaderboard.
Regarding her hole in one, she said: "I couldn't see it and the crowd didn't want to yell because Laura (Davies) was hitting off on 17, so we walked up there and they were like, 'it went in'!
"Yesterday I hit a full 7-iron over the green (for bogey) and it was basically the same yardage today, so I hit a softer 7-iron. It covered the pin the whole way and I just saw it bounce once and hit the pin but I didn't see it go in."
Lee just two shots off the pace
World No 2 Pettersen, who led after her opening 66, had five birdies and a bogey in a second-round of 68 and she sits at 10-under.
And 17-year-old Aussie amateur Minjee Lee remains right in the hunt after a 67 left her at nine-under, two behind Hedwall.
Nordqvist is in a group of three at eight-under after her flawless course record round, which featured neatly-spaced birdies at one, three, five, eight, 11, 13, 15 and 17, and no bogeys.
Cheyenne Woods, niece of Tiger, bounced back from an opening 74 with a fine round of 65 and she is in a tie for 20th at five-under-par but British Solheim Cup star Charley Hull is three-over after a 75.
