The 26-year-old carded a 6-under par final round of 65 for a 16-under par total to win by one from Thailand’s April Angurasaranee and Korean amateur Soomin Oh.

The win is Laisne’s first on both the WPGA Tour of Australasia and the Ladies European Tour, having previously won twice on the LET Access Series as an amateur in 2020 and on the Epson Tour in 2023.

“I knew nothing (out there). Nothing. I just tried to make as many birdies as I could,” she said. “I felt the pressure because I knew people were around (watching us), so it could have been me, could have been someone else. I didn't know. So I tried to make the best shots as I could, even with all the pressure I had.”

Laisne started her tournament with a 1-over 72, played during heavy rain on Thursday morning, which later led to the suspension of the entire afternoon. She then played her second and third rounds on Saturday, moving to within two strokes of the lead going into the final day.

“Round one, we had a lot of water. I was soaked,” she added. “I had never seen that before. My shoes had water in them, I could pour water out of them. So I think plus one was okay. I think it was worth a four under in good conditions, so I was pretty happy with it, and I tried to take opportunities when we had good weather on the 36 holes on Saturday, and it worked out.”

Despite moving into an early share of the lead after birdies on the second and third holes, Laisne found herself chasing for most of the afternoon as 17-year-old Oh made eight birdies in 11 holes from the fourth.

Laisne was three behind with six to play before she moved back into contention with an eagle at the 13th to reach 15-under. A fifth birdie of the day at the 17th saw her move back to the top of the leaderboard alongside Oh on 16-under after the Korean dropped a shot at the 16th.

Just as Laisne teed off on the par five 18th, Oh carded another bogey after hitting her approach to the final hole over the green, giving the Korean a share of the clubhouse lead on 15-under with Angurasaranee.

Laisne then laid up and hit her approach to the heart of the green, giving her two putts from 30 feet to seal the victory, joining compatriot Joanna Klatten as a name etched on the Jan Stephenson Trophy, which was then presented to her by the three-time Major Champion at the conclusion of play.

Charlotte Heath (England) finished fourth on 13-under, while Sydney's Sarah Kemp ended the week as the leading Australian in a share of fifth on 12-under.
