Joseph O'Brien, who like Hickmott has prepared two Melbourne Cup winners for leviathan owner Lloyd Williams, has two entries, headlined by favourite Al Riffa, while his father Aidan paid-up for three horses, including Scandinavia.
England, France, Japan, Germany and the United States are the other countries represented with Jordon revealing that legendary jockey John Velazquez had been booked to ride American entry Parchment Party, who owns a ballot exemption thanks to his golden ticket win in the Grade 2 Belmont Gold Cup.
"The breadth of the nominations from England, Ireland, France, Germany, USA and Japan is probably the widest breadth of nominations we've had," Jordon said.
"The depth is really strong, not just internationally but domestically. So, his year, the 165th running – the first time the Lexus Melbourne Cup has been run at $10 million – should be fantastic."
The next significant development regarding this year's Lexus Melbourne Cup comes on Tuesday 16 September, when Racing Victoria chief handicapper David Hegan will release the weights for the race that will be run on November 4.
