Ormsby began his second round superbly with three consecutive birdies and when he added another at the 7th he was able to make the turn in 32 and was contending for the lead.
He would, though, bogey five of his next eight holes before a birdie at the last was at least some consolation.
Ormsby finds himself in a share of 27th in the 60 man field and faces a big task if he is to share in some of the richer spoils of the event.
Australia’s other player to have made his way into the elite field, Lucas Herbert, improved on his opening round of 74 to record 70 today but is tied for 43rd.
New Zealander Ryan Fox has recorded consecutive rounds of 74 to be tied for 54th.
The leader is England’s Matt Wallace who has opened up a three shot lead his fellow countryman Jordan Smith who shares second place with Spain’s Adrian Otaegui.
“That's up there with one of the best this year," said Wallace of his round of 65.
"With it being in round two, as well, it's nice. Haven't done that much this year, improving on the first round. I seem to play really nice the first day and just go backwards. That was nice today and hopefully more on the weekend.
“I've got rid of all the expectations that have come with playing well and winning; I've expected higher from myself and that's just killed me. So I'm playing with freedom now and trying to place as high as I possibly can come the back nine holes on Sunday.
"That's when I normally will try and kick in and want to win a tournament, depending on where I am. Last week was the best week I've had mentally because I've had no expectations and I finished fifth. That's nice.”
Rory McIlroy a two time winner of the event is well enough placed at 8 under and just three from the lead in 6th place, a position he shares with Tommy Fleetwood amongst others.
“I have to be pleased," said McIlroy. "It's a massive improvement considering the golf I've played the last couple of weeks. So to shoot two scores in the 60s is great. I feel like today was even an improvement on yesterday."
