The Queen is to have a horse in training in Australia, with the 2011 Derby third Carlton House set to travel on to Gai Waterhouse’s stable in Sydney following his run in Sunday’s Group 1 Hong Kong Vase at Sha Tin.

Trained by Sir Michael Stoute, the four-year-old son of Street Cry, who was a gift to the Queen from Sheikh Mohammed, won the Group 2 Dante Stakes at York and started favourite for the Derby but could manage only a placed finish behind Poir Moi and Treasure Beach. He won the G3 Brigadier Gerard Stakes at Sandwon on his seasonal resumption this year and was runner-up to So You Think in the Prince Of Wales’s Stakes at Royal Ascot.

“Carlton House looks the perfect candidate to race in Australia where there are a number of options for older horses,” said the Queen’s Racing Manager John Warren. “It is an exciting plan and a wonderful opportunity for Her Majesty to have a horse that can participate in Australia.”

Earlier this year, Gai Waterhouse took charge of another former Sir Michael Stoute-trained colt, the four-year-old Fiorente, who was runner-up to Green Moon in the Melbourne Cup on his first start in Australia.
