See the 2021 Australian Guineas Preview and Results.
The first Australian Guineas was run in 1986, making it a relatively new race. It is Set Weights over 1600m with a 2kg allowance for fillies. In 1986 it was a Group 3 race and the inaugural winner was the class horse True Version. From 1987 on it has been a Group 1 race. In 1998 the Cadbury Australian Guineas became the third leg of the inaugural Australian Triple Crown for Three Year Olds and was ran over 2000m on Australian Cup Day in 1998, 1999 and 2000.
In 2001 the Guineas reverted to its original distance and date of mid-February. In 1995 there was a re-structure of VRC autumn metropolitan race dates and programs, and the 2005 Cadbury Australian Guineas was run on Newmarket Handicap day as part of the VRC’s Super Saturday, which is the first day of the Flemington Festival of Racing.
Prizemoney for the race is $1,000,000 and in 2007 it was run at Caulfield, as Flemington track was being reconstructed.
When Mystic Journey won in 2019 she was the first Tasmanian trained horse to win a Group 1 equivalent race in 133 years when Malua won the 1886 Australian Cup. She also became the 5th filly to win the race (the first since Mosheen in 2011).
