Australia's most outstanding three-year-old Zoustar gave his new connections a thrill when he scored a brilliant win in Saturday's Group One Coolmore Stud Stakes at Flemington. One of two Group One winners on the card for premier Sydney horseman Chris Waller, Zoustar came from last with a sustained sprint up the famous Flemington straight to win by a widening two length margin.

Having now firmly established himself as Australia's best three-year-old and the country's hottest and most exciting galloper, Zoustar could be headed abroad with a tilt at next year's Royal Ascot Carnival a strong possibility.

The win was a triumph for jockey Jim Cassidy, his 100th win at racing's elite level, making him just the third champion rider in Australia to do so.

Zoustar was sent out a warm favourite after winning the Group One Golden Rose two starts back and a breathtaking Group Two victory, also in Sydney, at his most recent outing.
