In an open contest, Princess Rihanna has been installed a $4.80 favourite and will have the services of Michael McNab.
Four-year-old Ocean Park mare Hibernia Sea gets a good chance to break maiden ranks and is rated a $5 chance in the Malcolm Wrigley Insurance 1300.
"She has drawn out a little bit and will need a bit of luck from gate nine and if she gets a bit of luck in the running, she will be competitive.
"She has been placed a few times and she is going to get better with time, but she is a seven-start maiden."
Meanwhile, veteran stayer Charles Road is back in New Zealand after a disappointing Sydney campaign and will contest the weight-for-age Group Three Jarden Stakes (2000m) at Ellerslie on Melbourne Cup Day.
"He has been back a couple of weeks and we will take it race by race with him. As long as he is going well, we will look at some of the Cups races with him," O'Sullivan said.
"It is very difficult for a horse like him because he is going to be asked to carry top weights every time he goes around, just because of the lack of depth of the stayers here.
"He is penalised for something that he did two or three years ago."
Two years ago the David Archer-owned stayer ran a bold race when seventh to Cross Counter in the Melbourne Cup.
O'Sullivan also reports three-year-old Rocket Spade will contest the Group One 2000 Guineas (1600m) despite being beaten six lengths into fourth in the Group Two James And Annie Sarten Memorial Stakes (1400m) won by Need I Say More.
"We are going to change the gear on him a little bit and try something a bit different but off that run, he is going to have to improve. It's as simple as that," O'Sullivan said.
Spring Heat will resume in the Legacy Lodge Sprint (1100m) at Te Rapa on November 7, while Summer Passage will contest the Haunui Farm Counties Bowl (1100m) on November 21. - NZ Racing Desk
