Tony and Calvin McEvoy have nominated three runners, headed by defending champion Half Yours.
Ireland is strongly represented, with Joseph O’Brien responsible for 15 nominations, including last year’s Melbourne Cup runner-up Goodie Two Shoes.
Aidan O’Brien has just one nomination, G2 winner Causeway.
The Melbourne Racing Club announced in June that prize money for the 150th running of the Caulfield Cup would rise from $5 million to $6 million.
The winner will receive $3.3 million, while connections of all 18 starters will earn prizemoney, with horses finishing outside the top 10 collecting $60,000.
Australian Derby winner Green Spaces, trained by Bjorn Baker, is the current $9 pre-post favourite.
Aeliana is next at $11, with Half Yours and Sir Delius on the following line at $15.
Late nominations will be accepted until midday on Tuesday, September 8, before weights are released on Thursday, September 17.
First declarations will be taken on Tuesday, September 22, second declarations on Tuesday, October 6 and the final field will be announced on Tuesday, October 13.
