On this course last year, Ko was within sight of victory before she three-putted the 18thfor a double bogey causing her to lose to Caroline Hedwall by one stroke.
That day, she finished the tournament at 10-under.
Now 14, slightly taller and considerably wiser, Ko projects maturity and composure beyond her years to show up a field that includes former World No.1 Laura Davies, Australian Open hopeful Melissa Davies and Australian leading lights Katherine Hull, Rachel Bailey and Nikki Garrett.
Wright had the clubhouse lead with a bogey-free round, before watching it melt away under Ko's hot streak. Wright, who reached a high of 12th in the world in 2009 before two disappointing seasons, hopes to turn over a new leaf in 2012. She has already posted a top-20 finish at the Victorian Open and a top 10 at the Canberra Ladies Classic.
She said aggression was the key to her best round in more than two years.
"I played at the flag, aggressive," she said. "My shots didn't leave the flag. Everything was for birdie today. I wasn't trying to scrape around to save par which I've been doing."
Overnight co-leaders Rachel Bailey and Karen Lunn failed to capitalise on their strong opening, with Lunn dropping five shots while Bailey stayed even at four-under-par to remain in contention today.
