Major winner Hannah Green ended a 12-year wait for a local player to triumph at the Australian Open, holding off compatriot Cassie Porter and France's Agathe Laisne by a shot on Sunday.
The world No 9 is in a rich vein of form, having won her seventh LPGA Tour title a fortnight ago in Singapore, and carded a steady 70 to end at 11-under for the tournament.
Not since seven-time major champion Karrie Webb lifted the trophy for a fifth time in 2014 has an Australian tasted victory in their home Open.
"I'm a bit speechless to be honest," said Green, who like in Singapore had husband Jarryd Felton – also a professional golfer – on the bag.
"I think the win in Singapore definitely helped with my nerves today. I felt a little bit more in control of my golf ball.
"Just really happy to have my name on that trophy among all the amazing other winners, as well as Webby," she added.
The 29-year-old, the 2019 PGA Championship winner, took a one-stroke lead into the final round from Argentina's Magdalena Simmermacher, who faded to finish five off the pace.
Porter (62) and Laisne (67) began charging at Kooyonga Golf Club in Adelaide.
It was all square with Laisne before Green sunk a clutch birdie at the 16th to pull a shot clear of the French golfer, who was playing in the group in front and bogeyed the 17th.
Porter launched a stunning final-round assault, sinking an unblemished 10 birdies to be in the clubhouse at 10-under.
And when Green bogeyed the 17th, it set up a tense finale at the last with a par or better needed.
She safely two-putted the 18th for par to clinch victory and spark a champagne celebration with her caddie husband.
Australia's other two major champions, Grace Lee and world No 4 Minjee Lee, finished 10th and 29th respectively.
