Gold Front Thoroughbreds has trumped the rest of Western Australia with the first foal by its Group 1 winning Fastnet Rock stallion Awesome Rock.
His filly from Herculian Princess (O'Reilly) arrived on Thursday morning.
Gold Front owners Alan and Sue Olive bred and raced Awesome Rock to a career-high victory in the 2016 Mackinnon Stakes at Flemington and he retired to their 300-acre property near Gingin last year.
"Mother Nature waits for no one," Sue Olive said. "The filly is a fortnight early but is a lovely type and already loves a pat and cuddle. Mum and Bub are both doing really well."
The Olives kept a share in Awesome Rock after he made $575,000 at the 2013 Gold Coast Magic Millions.
Among the other part-owners was Stan Saric who sent Herculian Princess west to be part of his first book.
She is a half-sister to Group 1 winner Herculian Prince (AJC Metropolitan Hcp) and will stay in WA to be bred back to Awesome Rock who stands for an $8,000 service fee.
