Connections of top sprinting three-year-old Zoustar are hoping for a flight to England next Sunday as the countdown to Royal Ascot intensifies. The Chris Waller trained colt is likely to be the sole Australian representative at the famous carnival in June with stablemate Sacred Falls now unlikely to make the trip.

A final decision on whether Sacred Falls will contest the Queen Anne Stakes is expected to be made later in the week.

Widden Stud boss Antony Thompson said a flight was not yet confirmed for Zoustar but hopeful of it being arranged for Sunday.

Thompson also said a decision would be made on who will ride Zoustar in the Diamond Jubilee once the horse settles in to his new surroundings. Jim Cassidy is in the mix but is not certain to make the trip across to England for the Group 1 race on June 21.
