Former Walker Cup player Cormac Sharvin posted an opening round of 68 to leave himself in a strong position after day one of the Perth International.
The Ardglass golfer, who was unbeaten during Great Britain and Ireland’s victory over the USA last year, birdied seven holes and sits tied for fifth place.
He is currently three shots off the lead of America's Peter Uihlein who recovered from an opening bogey to card an impressive 65.
Elsewhere Paul Dunne is well off the pace after scratching his way to a one over par round of 73, while Michael Hoey sits five over par.
Uihlein produced the shot of the day on his way to reaching the top of the leaderboard.
The American made an encouraging return from a wrist injury at last week’s Maybank Championship and made further progress in his rehabilitation with his 65 at Lake Karrinyup Country Club.
Uihlein, whose sole European Tour victory came in 2013 at the Madeira Islands Open, leads Romain Wattel and Shiv Kapur by one stroke after reaching seven under with six birdies and an eagle.
The 26-year-old did start his round with a bogey but after swiftly picking up three shots he stunned fans gathered around the four-par ninth hole by sinking his approach for an eagle.
He overtook early starters Wattel and Kapur with three more birdies on the back nine. Strong winds meant he had to make a tough recovery shot on the 15th after hooking his tee shot towards trees.
“I was mentally sound,” the man from Massachusetts told Sky Sports 4. “I didn’t really let the bad shots turn me.
“I putted nicely which is always helpful but if I didn’t hit a good shot I didn’t really let it bother me, I just let it roll off my back and I was ready for the next one.”
“When it’s in the wind like this, you’re going to hit bad shots, everybody does so you’ve just got to accept it and move on from there.”
France’s Wattel, who mixed eight birdies with two front-nine bogeys, had already posted his lowest score of the season so far while 34-year-old Kapur of India enjoyed a blemish-free round of 66.

Defending champion Thorbjorn Olesen signed for 71 while Ryder Cup winner Victor Dubuisson was five over after closing out a disappointing round with a birdie on the last.
John Parry also had a day to forget — the Yorkshireman was eight over at the turn.
