Since the 1980s, the Greyhound Owners Breeders and Trainers Association (GBOTA) has been the primary tenant of Wentworth Park (previously sharing with the now defunct NSW National Coursing Association Club). Greyhound racing is held at the venue every Wednesday and Saturday nights from 7.30pm. The biggest event of the year at Wentworth Park is the Group 1 Golden Easter Egg which provides prize money of 1,000,000 across the Easter carnival. The Carnival attracts approximately 25,000 racegoers. The final night is held annually on Easter Saturday.
