Former world No 1 Jiyai Shin overturned a three-stroke final-round deficit to claim a sixth-shot win and 50th career title at the ActewAGL Canberra Classic.
Shin chalked up the 50th title triumph of her card after closing with a brilliant eight-under-par 64 at Royal Canberra, where the 29-year-old Korean also won the 2013 Women's Australian Open.
In her prize-giving speech, Shin delighted the galleries by telling them that she was hitting the ball longer than ever because of the protein in the local Aussie meat pies.
"I have great memories from that final round battle with Lydia Ko and now this time with Minjee Lee: two great young ladies".
Western Australian Lee, who had won the previous week's Oates Vic Open, had been highly favoured to win after carding a nine-under-par 63 in the second round, but she ended with a disappointing one-over-par 73.
Anne Van Dam topped the European interest and finished seven shots back in third spot ahead of Pernilla Lindbergh, with England's Holly Clyburn ending the week in fifth place.
"I'm so excited I can't tell you", she added.
"It was a good start to the year and I played some great shots so I want to take it to the next event", Shin said.
On the final day, Aditi had six birdies against three bogeys.
The two-time LET victor was three-under after six holes before dropping four shots in three holes.
Solheim Cup captain Catriona Matthew (70) and Michele Thomson (74) tied for 15th on three-under.
