Hall of Fame trainer Waterhouse is no stranger to sourcing a star from the Magic Millions Gold Coast Yearling Sale, with stable stars Farnan, Vancouver, Alligator Blood, Global Glamour all purchased from the iconic January auction.

The stable's highest-priced purchase was $1.4 million for Lot 445, the Justify colt out of champion race mare Sunlight, while they also teamed up with McKeever Bloodstock and Watership Down on a $1m Too Darn Hot filly, out of two-year-old Stakes winner Enbihaar.

Ciaron Maher and David Eustace also used the sale as a chance to replenish their stocks, with the operation also involved in at least 30 purchases.

Maher paid more than he ever has on a yearling when he placed a winning bid of $2.5m on the I Am Invincible x Booker colt, while he also parted with $800,000 to secure the Pierata filly out of his former star sprinter Loving Gaby.

China Horse Club, in conjunction with Newgate Farm and Trilogy Racing, grossed more than $10m with 18 purchases.

And while they may not have bought the same volume of horses, Coolmore's Tom Magnier, James Harron's Colts Partnership and USA-based Tammy Rigney all opened the purse strings.

Magnier spent $4.95m on three yearlings, including the sale-topping $2.7m I Am Invincible x Anaaheed colt.

With a similar aim of unearthing a stallion prospect, Harron's Colts Partnership made five purchases totaling $4.75m, while Rigney bought two I Am Invincible fillies for a collective $3.2m.
