Fellow three-year-old Graff and the Darren Weir-trained four-year-old Nature Strip have been installed equal $8 favourites.
Three-time Group One winner The Autumn Sun has also been nominated for the Australian Guineas which has attracted 120 initial entries.
He is listed as doubtful to contest the race but heads the market at $3.50 ahead of Thousand Guineas winner Amphitrite, Group Two-winning Tasmanian filly Mystic Journey and Sandown Guineas winner Ringerdingding at $8.
