In 1996 and 2023 the event was held at Flemington Racecourse.
Notes:
 † The 2016 race was won by Azkadellia [36]  but was disqualified by Racing Victoria because convicted criminal Peter Foster was the 'mastermind' behind an arrangement with her racing manager Ben Connolly to deceive stewards over the true ownership. [37]
