Rosemont owned and reared Thrillster is giving her collection of part-owners a bit to get excited about making her not only one of the best 3yo fillies of her generation but certainly the best named!


As is so often the case in thoroughbred racing, the coming together of a big crew of owners is a story in itself and started back in the paddock when Thrillster was just a foal. Although you could argue it started even before that.

Rosemont client and breeder Richard Boyd and his partner Christine had a mare at the stud they thought would suit the then resident stallion Starspangledbanner. Doing a deal to foalshare Heart of Thrills to the Banner, she foaled a lovely colt who through complications after birth died not long after.

With the resilience of so many in this industry, Richard and Christine picked themselves up and went again, this time deciding to pay for the Starspangledbanner nomination and own the filly their mare produced, this time with no problems.
As traders and big cattle business owners, Richard and Christine asked Rosemont’s Anthony Mithen and then Bloodstock man Dean Harvey to keep a lookout for a quick trade on the filly, leading Mithen to buy her.

The Banner filly then grew out to become a lovely, uncomplicated athletic yearling, offered at Melbourne’s Inglis Premier sale, sold to the man who knows Starspangledbanner better than any – his former trainer and selector as a yearling Troy Corstens.

Sold for $60,000 on “spec”, Mithen told Corstens after the sale he would be happy to keep a leg. Racing gods stepped in and brought Mithen and Richard and Christine together again when the couple bravely and sensibly bought back into the filly’s ownership along with a big group of Corsten’s owners.

A very happy group of owners

Troy himself kept a share too, giving the trainer extra reason to smile at the Valley on Saturday.
Another group came in after purchasing a donated share at a Brainwave charity auction while Rosemont increased their ownership when another quarter of the filly was still left unsold several months after she was broken in. Lucky us!!!

In five starts, Thrillster has now won 3 and been placed in the other two (which were both Stakes races). She’s won $442,000 in prizemoney and it appears her best is still to come.
Team Corstens is now considering a tilt at the G1 Golden Rose in Sydney in a fortnight before tackling the G1 Thousand Guineas at Caulfield, a track she’s already excelled at winning the Gold Rush and placed in the G3 Quezette Stakes.

Either way, it’s going to be a thrilling spring for all involved, no matter how they got involved.
