A blistering eight-under par 64 - the best score of the week by two shots - has put Belgium's Manon De Roey into a two-stroke lead after 36 holes of the Women's NSW Open.
The 29-year-old scorched the Dubbo Golf Club course with five birdies and two eagles against a lone dropped shot to jump to nine-under-par overall with two rounds remaining.
De Roey - who has yet to win an event on the Ladies European Tour - has adapted well to the narrow Dubbo course and will look to maintain her form.
"My tee shots are pretty good normally," she said. "But this course is very tight.
"I'm confident about my driving but I still didn't hit too many fairways today.
"So for the weekend I will just try to keep doing what I've been doing. Finding the fairways, hitting the greens and trying to get close to make some birdies."
De Roey lies two shots clear of Sweden's Camilla Lennarth, India's Diksha Dagar and France's Agathe Sauzon.
A further shot separates that trio from overnight co-leader Michele Thomson, of Scotland, and Sweden's Julia Engstrom.
Leading the Australian charge is Soo Jin Lee, at 11th equal with three-under, while Breanna Gill shares 14th at one shot further back.
Last week's winner of the Australian Ladies Classic at NSW's Bonville course, 19-year-old Steph Kyriacou, missed the cut in her first professional start with disappointing rounds of 75 and 76.
