South Australian Jack Buchanan, New South Welshman Jeffrey Guan and Victorian Max Charles will join New Zealand’s Kazuma Kobori in making their debuts as professionals this week on the Challenger PGA Tour of Australasia.

Guan and Buchanan were both members of Australia’s Eisenhower Trophy team that finished tied for second in Abu Dhabi two weeks ago and played the Asia-Pacific Amateur Championship at Royal Melbourne Golf Club last week.

"For me, I think it was as soon as I finished last year. I had some really good results in the starts that I was given and I felt like if I could just match up my game to that then obviously, I can take that to a higher level and more opportunities would open up,” Guan said on the eve of his pro debut.

As fellow Victorian Jasper Stubbs prevailed in a play-off to book his place in The Masters and The Open, Charles finished as the next best Aussie in a tie for fourth.

Charles will be the first to tee off his professional career at 6:52am AEST on Thursday morning with Buchanan (11:06am) and Guan (11:56am) to follow in the afternoon wave.

“It is a big moment for sure. I haven't really thought about it. Yesterday was the biggest one for me, realising I'm starting to play for money now. It's exciting,” Charles said.

With the chase for Order of Merit honours now well and truly underway, PGA of Australia Tour Development Manager, Kim Felton, is thrilled to see the trio begin their professional careers on home soil.

“Jeff, Jack and Max have all had wonderful amateur careers and we’re excited to see what lies ahead of them as professionals,” said Felton.

“We have worked hard to develop the pathways that will give our best players the best opportunity to advance to the international stage.

“David Micheluzzi showed last year what is possible with a strong season on the Challenger PGA Tour of Australasia and I’ve got no doubt these three will have their eyes on something similar to kick-start their careers.”

The Queensland PGA Championship will also serve as the professional debut for Kiwi Kazuma Kobori, who was the individual winner at the Eisenhower Trophy two weeks ago and who last week finished sixth at the Asia-Pacific Amateur at Royal Melbourne Golf Club.
