Kai Komulainen of Queensland had his own moment of turning back the clock by seizing the lead in the men’s amateur with a 6-under par 64 at Yarra Yarra Golf Club in tricky, hot conditions.

Komulainen led through one round of the tournament in Sydney this time last year before dropping outside the top 20 through the week.

Komulainen is a shot ahead of New Zealander Mitchell Kale, who shot a bogey-free 5-under 67 at Keysborough, and another shot ahead of Noah Kent, who shot a 4-under 68 at Keysborough.

Yarra Yarra Golf Club local Phoenix Campbell opened with 1-under 69, and Jasper Stubbs, the winner of the 2023 Asia-Pacific Amateur, struggled to an opening 5-over 77 at Keysborough.

Komulainen had a 7:39 a.m. tee-off at Yarra Yarra, where a fierce overnight storm had left pools of water on low parts of the course and flooded many of the bunkers.

But the wind was down for the first part of his round, and he capitalized on it nicely with six birdies, two bogeys, and an eagle at the short par-4 fifth hole, where he drove the green.
