Gai Waterhouse

Gabriel Marie "Gai" Waterhouse (née Smith; born 2 September 1954) is an Australian horse trainer and businesswoman. The daughter of Tommy J. Smith, a leading trainer of Thoroughbred racehorses, Waterhouse was born and raised in Sydney. After graduating from the University of New South Wales, she worked as an actor for a time, appearing in both Australian and English television series. Having worked under her father for a period of 15 years, Waterhouse was granted an Australian Jockey Club (AJC) licence in 1992, and trained her first Group One winner later that year.

In 1994, after her father became ill, she took over his Tulloch Lodge stable, and she has since trained 145 Group One winners and won seven Sydney trainers' premierships. She was also the trainer of Fiorente, the winner of the 2013 Melbourne Cup, becoming the third woman (and first Australian woman) to train a winner of that race. Waterhouse was inducted into the Australian Racing Hall of Fame in 2007, and has been described as the "first lady of Australian racing".

Background and early career Waterhouse is the daughter of Valerie and Tommy J. Smith , a leading trainer of thoroughbred racehorses, who was based in Sydney. She was educated at the Convent of the Sacred Heart, Rose Bay (now Kincoppal-Rose Bay) in Sydney, and completed a Bachelor of Arts at the University of New South Wales in 1975. Waterhouse made a name for herself as a model and actor, including in the Australian drama The Young Doctors before moving to England and appearing in the Doctor Who story The Invasion of Time. She then returned to Australia where she served an apprenticeship under her father for fifteen years before gaining her trainer's licence. Waterhouse also won the 2010 BMW Caulfield Cup with Descarado. In the 2012 Caulfield Guineas Waterhouse's hot favourite Pierro, undefeated in his first eight races, was beaten by All Too Hard in a major upset. All Too Hard is the half-brother of star sprinter Black Caviar. In the Caulfield Cup, Waterhouse was dealt yet another blow when favourite Glencadam Gold finished 15th, nine lengths behind last year's Melbourne Cup winner Dunaden.

At the 2013 Sydney Cup day, owner John Singleton sacked Waterhouse live on television after her son Tom Waterhouse, a bookmaker, allegedly told acquaintances that Singleton's horse More Joyous would lose the All Ages Stakes, which it did. Both Gai Waterhouse and Tom Waterhouse denied any wrongdoing. Stewards laid two charges against Waterhouse; (1) 'fail to report to the stewards any condition or occurrence that may affect the running of a horse in a race', and (2) 'having failed to keep a record of treatments administered to a horse'. On 27 May, Waterhouse was found guilty and fined $5,500.

On 5 November 2013, Waterhouse won her first Melbourne Cup with Fiorente. She is the second female trainer to win the race, and the first Australian woman.

Awards

On 30 September 2000, Waterhouse was awarded the Australian Sports Medal for "outstanding contribution to thoroughbred racing". She is also an Australian Living Treasure nominated by the National Trust of Australia. Waterhouse was inducted into the Australian Racing's Hall of Fame in November 2007, following in the footsteps of her late father, T. J. Smith.
