Korean golfer Hyun Ju Shin missed a putt from less than a metre to hand shocked English veteran Lisa Hall a dramatic victory in the Australian Ladies Masters at Royal Pines.

It was Shin's only blemish in her four-under par 68 in Sunday's final round but it was enough to cost her a win in the rain-shortened 54 hole event.

Hall, 40, was expecting to head into a play-off but instead found herself making a victory speech after firing a flawless 66 in windy conditions to finish with a 13-under total 203 and collect $90,000 in prizemoney.

Defending champion Karrie Webb, a six-times winner of this event, again struggled with her driver en route to a fifth place in a mixed day featuring an eagle, three birdies and three bogeys.

"I think it was always going to be a day where it came down to the end," said Hall, who had just two bogeys over the entire three days of competition.

"It was going to take a low score so in that respect I wasn't surprised.

"I had time to mark my scorecard so seeing her (Shin) miss was like 'I won'! It was cool."

Florida-based Hall went to the Gold Coast casino on Tuesday night and bet on her lucky number 11 on her first roulette spin, a win she jokingly said proved a good omen for the rest of the week.

Shin, 28, played in the same group as fellow overnight leaders, Webb and Brisbane resident Tamie Durdin, who crumbled under the pressure to card a 79 after starting the day at eight-under.

"I am a little disappointed because I played really well in three days and I never missed a short putt, but there was pressure," said Shin, who broke down crying following the heart-breaking loss.

"It was a bad stroke (on the 18th green)."

Hall thought she was "finished" as a professional golfer at the end of 2004 after missing the cut in 16 events on the LPGA Tour.

She confessed she couldn't even hit the ball in the air but after missing the 2005 season, her husband Martin encouraged her to make a comeback on the European Tour.

Hall enlisted the services of former LPGA Tour player Mardi Lunn and eventually rediscovered her love of the game as she won two European events last year, both in play-offs.

Asked how she rated her victory over a field boasting world No.3 Webb, Hall replied: "To shoot six-under last round to beat Karrie Webb in Australia, it's going to be high up there."

Hall's compatriot Felicity Johnson carded a 65, the lowest round of the tournament, to tie for third with Swede Louise Stahle.

A nervous Durdin had a shocker, dropping four shots in her opening five holes to plummet out of contention.

She eventually tied for 23rd while another player to fade badly was Taiwan's Ya-Ni Tseng, who started the day at seven-under but carded a 79.
