Winx’s story began with John Camilleri’s purchase of her dam, Vegas Showgirl, for A$455,000 at the 2008 Magic Millions National Broodmare Sale. A dual stakes winner in New Zealand, Vegas Showgirl became part of his Fairway Thoroughbreds breeding operation. Winx was her second foal, born and raised at Coolmore Stud in the Hunter Valley.
The mating paired Vegas Showgirl with Street Cry, whose offspring already included American champion Zenyatta. Winx’s maternal family later produced her stakes-winning half-brother El Divino. Her name also carried a connection to her dam, inspired by Richard Treweeke’s memories of Las Vegas showgirls and the exchange of a wink.
Winx was offered by Coolmore Stud on behalf of Fairway Thoroughbreds as Lot 329 at the 2013 Magic Millions Gold Coast Yearling Sale. Selected by bloodstock agent Guy Mulcaster, she was bought by Peter Tighe’s Magic Bloodstock for A$230,000.
She raced for Tighe, Richard Treweeke and Debbie Kepitis, with their families remaining closely involved throughout her career. The yearling purchase brought together the ownership group that would accompany her through four Cox Plates and her eventual retirement.
Winx debuted at Warwick Farm in June 2014, winning over 1100 metres with Jason Collett aboard. She followed with a 1400-metre victory at Rosehill later that month, completing an unbeaten two-start juvenile campaign.
Winx returned to Coolmore Stud to begin her breeding career after retiring in April 2019. Her first foal, by I Am Invincible, was lost in 2020. She subsequently produced a Pierro filly in October 2022, marking a happier milestone after that difficult beginning.
The filly, later named Quinceanera, sold for A$10 million at the 2024 Inglis Australian Easter Yearling Sale to Debbie Kepitis’s Woppitt Bloodstock, setting a world-record auction price for a yearling filly. She was retired without racing in April 2026 to begin a breeding career.
Winx also produced a Snitzel colt in 2024. His planned appearance at the 2026 Easter Sale was cancelled following a preparation setback, with her owners prioritising his recovery on veterinary advice. In September 2026, Winx delivered a Too Darn Hot filly, her third surviving foal. Her connections reported that both mare and filly were healthy.
