Porter’s compatriot Green made another birdie before the turn at the short par-5 9th before Laisne made four birdies in a row at the 8th, 9th, 10th and 11th to tie the lead.
Having won the Ford Women’s NSW Open two weeks ago, Laisne would chip in for par at the par-3 15th to pile the pressure on the home favourite.
But two holes later, a big turning point as the Frenchwoman dropped a shot at the 17th with Green making an excellent birdie of her own at the 16th for a two-shot swing.
Green, a one-time Major winner at the 2019 KPMG Women’s PGA Championship, would also bogey the 17th giving her a one shot lead heading down the last. A par was enough to seal victory following a fortunate bounce of the tee followed by a nerveless approach into the green – one surrounded by Aussie supporters.
“It was tough,” Green said after getting the job done. “I felt like I was hitting the clubs that I needed to hit, but it wasn’t perhaps going actually near the hole, so it kind of was frustrating. I knew that people could come from behind today and not be in the last group, so I wanted to make sure that even though I was perhaps performing well amongst the group, I didn’t want to get too ahead of myself and know that there’s potential for a low round.
“That birdie on 16 gave myself a little bit [of a] buffer. But I like to make it really nerve-racking for myself and everyone watching. So I hope my next win is a little bit more cheerful!”
With Porter and Laisne ending the week T2 on 10-under par, another Australian, Karis Davidson, finished T4 on six-under par alongside South Africa’s Casandra Alexander.
Simmermacher ended the week solo sixth on five-under par after she reignited her best form following a difficult few years on the LET.
New Zealand’s Momoka Kobori, Wales’ Darcey Harry and Jana Melichova finished seventh at Kooyonga Golf Club on four-under par.
In the LET Order of Merit, Laisne now leads the way on 797.50 points following another excellent week in Australia. Australia’s Kelsey Bennett drops down into second on 670.25 points with Alexander now third on 540.83 ponts.
Next up on the LET sees the fourth and final event of the 2026 Aussie swing with a trip to the Gold Coast for the Australian WPGA Championship at Sanctuary Cove.
