A Deep Field x Blueridge Cat gelding, offered by Prima Park's Kely Van Dyke, topped the sale, selling to George Moore Bloodstock for $340,000.
The colt was originally purchased by Prima Park and Waterford Bloodstock as a weanling at the Great Southern Sale in Melbourne.
"He was a stunning horse, he breezed up exceptionally but to come here and be rewarded with the sale-topping price is pretty special,'' Van Dyk said.
Moore purchased a Deep Field colt at the Easter Yearling Sale earlier this year for $425,000 and said that particular colt had done so well, he wanted another one in his stable.
"This horse has the right temperament and a nice big action on him,'' Moore said.
"He was one of the nicest Deep Fields here. We were actually on two of them but I liked this one a bit more because he looks to be more of a speed horse.''
Moore was one of several Hong Kong buyers along with others from China, Macau, New Zealand, Singapore and Thailand.
Among the domestic buyers were Mick Price, Bjorn Baker, Anton Koolman, Andrew Williams, Mark Newnham, Kim Waugh, Darby Racing, Aquis Farm, Ciaron Maher, Lloyd Kennewell, Ellerton Zahra Racing, Daniel Bowman, Brett Cavanough and Barbara Joseph.
Wyong trainer Damian Lane of Glenvale Park - which he runs with his father-in-law Bob Law – had a day to remember.
He offered the second top lot, a Deep Field x Prinny's Girl colt which sold to Horse Feng Bloodstock for $320,000 after Lane had purchased him for just $21,000 at Scone in May but he also secured $140,000 for a Real Impact x Madison Park colt to Hong Kong trainer Casper Fownes originally bought for $25,000 at the Classic Yearling Sale.
"It's been phenomenal, those two results,'' Lane said.
"This is huge for us. That type of money, it's unheard of to be honest. I was getting pretty emotional to be honest.
"Good luck to the buyers, I know you have bought great horses.''
Blake Ryan enjoyed similar results, including a Real Impact x Only Roses colt which sold to Andrew Williams Bloodstock for $310,000, making it the day's third-top lot, as well as a Headwater colt which sold for $240,000.
"It's very satisfying. I can reinvest in confidence now at next year's Classic Sale," Ryan said.
The sale realized an average of $79,207 and a gross of $7,841,500.
