The Grand Prix has been dominated in recent times by champion Sydney trainer Chris Waller.
Waller has won the feature five times since his first victory with Hawkspur in 2012.
His other Grand Prix winners include Vilanova (2013), Mackintosh (2015), The Elanora (2020) and last year with Kovalica.
Kovalica went on from his Grand Prix triumph to claim the Group 2 Queensland Guineas and Group 1 Queensland Derby at Eagle Farm last winter.
The son of Ocean Park then finished second in the Group 1 Epsom Handicap at Randwick, which was won by stable mate Rediener during the spring.
