The English player held her nerve and holed a three foot par putt to win the NSW Open at Oatlands Golf Club in Sydney.
With rounds 69, 66 and 70 she finished on top of the leaderboard at 11-under-par and just one clear of NSW's Rebecca Artis (68), Austrian Christine Wolf (64), Scotland's Vikki Laing (67) and Switzerland's Fabienne In-Albon (69).
The NSW Open is renowned for exciting finishes and at one stage mid-way through the back nine, five players shared the lead at 10-under-par. It was a birdie on the par 4 14th hole which proved crucial.
Clyburn hit her 3 wood off the tee, then her wedge into the green, she left herself with a 9 foot birdie putt which she calmly rolled in to break away from the group of players at 10-under-par.
It was the 24-year-olds third professional victory after wins on the Ladies European Tour (LET) Access Series and LET. She was delighted,
"It means a lot, a have been knocking on the door for a few months now, I have been working hard and did not have any expectations this week after last week, so yeah, it has just been great and a weight has been lifted off my shoulders."
NSW Nikki Garrett (70) finished outright sixth at 9-under-par, while Victorian Stacey Keating (66), South Australian Tamie Durdin (68) and NSW's amateur Shelley Shin (69) shared seventh a further shot back.
