Then he hopes to do the same in the USA.

Armstrong won the Murray Open in Corowa on Wednesday, shooting an equal-course record 63 on Tuesday before sealing a one-shot victory with a four-under 69 in the final day.

Western Australia's Daniel Fox finished second at 13-under, while Charlie Dann was one shot further back in third.

The win has earned him a start in the $400,000 NSW Open, which the coronavirus has turned into the biggest tournament of the Australian summer.

It will be played on his now home course at Concord, in Sydney, from March 25.

Armstrong only turned professional in December and spent Thursday travelling to the Dubbo Open, which starts on Saturday.

Then he'll be back in his home town for the Queanbeyan Open on February 24-25.

He hopes to do well enough over the remaining events to earn a spot on next year's PGA Tour of Australasia.

If not, there's the Tour's qualifying school after that.

Armstrong also has his eyes on the Korn Ferry Tour in the USA.

"I'll try and get my card in Australia before I go anywhere else, but I'd love to go over to America and go to the secondary tour in America ... hopefully later this year in August," he said.

"But we'll need to see what goes on with COVID, but that's kind of the plan at the moment."

He said the win still hadn't sunk in, but he was excited to get the first victory of his professional career.

After his stunning opening round, Armstrong's second got "a bit sloppy" before a sensational eagle on the 15^th hole drew him level with Fox.

Fox then bogeyed the 16^th to send Armstrong into the lead.

"That was the deciding two holes really. It was nice to be able to produce something when I needed it and put the pressure on," Armstrong said.

"It's pretty cool. I guess it hasn't sunk in much yet to be honest.

"But it's nice to know that I can do that and I have the ability to do that. I've only been professional since December so it's still very early days."
