Conor Purcell took advantage of a rare DP World Tour start as he moved into the top-10 down under at the ISPS Hands Australian Open.
Purcell is on two-under-par after a 68 and is five shots adrift of early leader David Micheluzzi.
The Portmarnock man had his front nine bookended by birdies before dropping his only shot of the day on 15.
The 25-year-old bounced back and finished in style with a closing birdie to share 10th place at the close of play.
Purcell is just two shots shy of second place.
2022 has been fruitful for the Dubliner who has had his early years as a professional curtailed by COVID, but he showed glimpses of what he can do during the Alps Tour season and on the Challenge Tour – earning status on the latter.
Aussie Micheluzzi leads by three after four birdies in eight holes saw him finish with a flourish and pull clear of Josh Geary and Matthew Griffin in second place.
Playing in his home open, the 26-year-old opened with a bogey on 10 but posted eight birdies without a blemish to soar to the summit.
