The 27 year old from the south coast of New South Wales drew on a season of strong performances and near misses to fire his second successive six-under-par 66 for a tournament total of 19 under, with defending champion Lee Chieh-po from Chinese-Taipei finishing runner up after an equally fine 67.

Chinese-Taipei’s Wang Wei-hsuan (67), Nicholas Fung from Malaysia (67), American Berry Henson (68), and Bjorn Hellgren from Sweden (69) tied for third, five behind the winner.

Smyth started the day with a one-shot lead and proved uncatchable after he birdied four out of the first six to make the turn in four under before virtually wrapping things up by making three birdies in a row from the 10th. With a healthy lead the surprise double bogey he made on the 15th, which were his only dropped shots of the day, was not too damaging particularly as he responded with his final birdie of the day on the next.

The victory made up for narrowly failing to win the International Series England in June where he was second – a result that earned him starts on the LIV Golf Invitational series.

“Feels amazing!” said an overjoyed Smyth, who picked up a cheque for US$126,000.

“I got so close, I felt like I let it go in England and to play some LIV events, feel what it’s like there, I just want to get back. I want to be the player that I believe I can be, and winning this week is one step along the journey.”

On the 15th his ball plugged in a bunker, after a big hook with his nine iron, from where he splashed out and three putted to make the closing stages slightly more interesting.

He becomes the 11th first-time winner this season, and first Australian to win the event.

He added: “The opening nine, or first five, six holes are quite easy, but it’s a tight course so you have to hit it straight. You got to be below the hole, you got to roll the putts in, and I just did exactly that. Set the pace for the day. But you know the guy I was playing with, Lee Chieh-po, he played amazing. I was always like one, two or three shots within him, and he kept playing well and applying pressure, so it wasn’t easy that’s for sure.”

Smyth earned his place on the Asian Tour by finishing joint third at Qualifying School in 2018 and after a number of good results since then, a first victory had been expected soon.
