Brett Prebble is an Australian jockey who first moved to Hong Kong in 2002, having already won two Melbourne premierships. For many years, he was Douglas Whyte's arch-rival, finishing second in the jockeys' championship six times, including a narrow loss on the final day in 2009-10. In 2010, he was the first jockey to ride six winners in a day, a feat since accomplished by Whyte and Joao Moreira. He has been associated with Hong Kong stars like Bullish Luck, Sacred Kingdom, Cape Of Good Hope and Lucky Nine.
