Japan's Haru Nomura has won the ISPS Handa Women's Australian Open today at Grange Golf Course.
Nomura finished with a seven under par 65 to blow the world's best away with a stunning display.
The 23 year old from Tokyo nailed long putts and gave the world's best Lydia Ko something to chase.
Nomura sank a 12 metre putt on the ninth hole to give her the outright lead and from here she could not be caught.
She went on to make five more birdies before having a bogey on the 18th this being her first bogey since the 12th hole yesterday.
But Nomura's putting was first class and even she was stoked with her work on the greens.
"The putter...wow...unbelievable," she said.
The world number 67 pocketed $US195,000 for the win and is the first Japanese winner since 1974 when Chako Higuchi held the trophy aloft.
Earlier in the day Australian star Minjee Lee was off to a flying start with birdies on the first two holes to put her within three strokes from the lead, however a bogey for the next two holes and she went back to four under and was too far back to challenge the leaders.
Lee finished T20 with four under par and worked really hard after her four over 76 on day two.
Australian veteran Karrie Webb claimed the lead with three birdies in the first five holes but this all the champion had left in her as she finished third at nine under.
With over 30,000 fans over four days at the prestigious Grange Golf Course shows South Australians continue to support the big events, this crowd number was even well above Golf Australia's expectations.
Next year its Royal Adelaide Golf Club's turn to host the Australian Open which will also celebrate the club's 125 year anniversary.
