The Winx Stakes takes place in late August, making it the first Group One of the Spring Carnival. The race is officially registered as the Warwick Stakes, but in 2018 had its name changed to honour the mighty mare Winx. 

The race's inaugural running was back in 1923 at Warwick Farm racecourse in Sydney's south-west. Since then, the venue has consistently alternated between Warwick Farm and Royal Randwick, with Canterbury Park Racecourse also hosting a solo running in 2000. Since 2014, every edition has been held at Randwick.

In 2018, as well as having its name changed from the Warwick Stakes to the Winx Stakes, the race was given Group One status. In a fitting result, Winx greeted the judge, making it three years on the trot that she has saluted in the race.

However, it's not just Winx that has had phenomenal success in the race over the years. Both Limerick (1927-1929) and Kingston Town (1980-1982) have likewise won the race in three consecutive years. Other multiple winners include Sky High, Super Impose and Lonhro, while champion horses Amounis and Tulloch have also tasted victory in the race.

Through their association with not just Winx but the 2015 winner Royal Descent, Chris Waller and Hugh Bowman have claimed victory in the past four editions of the Winx Stakes. Both will be gunning for five straight this year to get their Spring Carnivals off to the perfect start.
