BC3 Thoroughbreds outlayed $2.6m to secure champion mare Black Caviar’s half sister at the Australian Easter Yearling Sale in Sydney today.

The bidding on the Helsinge – Redoute’s Choice filly started at $1m before quickly skipping to $1.5m then bids came in at $100,000 increments.

BC3 chief executive Bill Vlahos said he felt a bit nervous as the bids climbed to $2.5m but when the hammer went down, the final bid was what he expected.

“At two-and-a-half million I got a little bit wobbly,” Vlahos said.

“We pretty much stuck to our price. We think she’s worth exactly what we paid for her. Too much more and it might not be us owning her.”

The filly will be sent to Danny O’Brien in Melbourne to train and not surprisingly he was very excited to be getting such a high profile yearling to prepare.

“It’s very rare a horse like this is offered for auction,” O’Brien said.

“Fillies like this would generally be retained by breeders, anyone lucky enough to breed a filly like this would be very loath to sell it.

“It was really a once in a generation chance to buy a filly like this. Not only obviously the pedigree but she was an outstanding individual herself.”

Super mare Black Caviar is undefeated from nineteen starts, amassing over $5m in prizemoney and is being prepared by Melbourne’s leading trainer Peter Moody for the Group 1 £500,000 The Diamond Jubilee Stakes (1200m) at Royal Ascot in England on June 23.

While the filly’s half  brother All Too Hard is also undefeated from three starts and will step out in the Group 1 $500,000 Inglis Sires Produce Stakes (1400m) at Randwick on Saturday.
