After the first hole on the final day, Halls had drawn level with O'Donovan, and by the second he was in the lead on his own. A third straight birdie on Commonwealth's to kick off his round confirmed that 20-year-old would not be looking back.

"I was very nervous teeing off with the tough conditions today," Halls said. "I played very smart though and took advantage of the downwind holes and played really solid all day.

"The first two holes are definitely very gettable and I did a good job of birding those two then yeah, got a bonus one on the third hole."

Halls' only bogey of the day came at the 11th after missing the green long, but the New South Wales Golf Club member brushed it off and proceeded to make three more birdies coming in just to make sure of things.

Although on the outside it looked as if nothing could unnerve Halls, he says that wasn't the case in reality, but his years on the cliffs at his home course helped him home.

"I was definitely nervous, definitely at the start, but they settled down towards the back nine," the former Mollymook junior said.

"We get a lot of wind out at New South and that definitely played a helping hand today.”

Halls came into this week with a number of accolades to his name, including the 2024 Queensland Strokeplay Championship, as well as the low amateur honours at last year's NSW Open, but an Australian Amateur is a huge addition to his resume.

"This definitely gives me a lot of confidence going into the next few tournaments," he said.

"Knowing that my best golf can win pretty much anywhere is huge, I look forward to the next few."
