Stage to Stable: Gai Waterhouse’s Biography
Born Gabrielle Marie Smith on September 2, 1954, Gai Waterhouse’s age is 70. She is the daughter of famed trainer Tommy “TJ” Smith (who trained a record 246 Group 1 winners,) and she grew up at Sydney’s Tulloch Lodge, surrounded by horse racing from a young age.
She initially focused on a career in acting, making appearances on shows like “Neighbours,” “The Young Doctors,” and the BBC series “Doctor Who,” but the attraction of the racetrack won out. In 1978, she gave up acting to work in her father’s stable as a clocker and client relations manager.
When she applied for her trainer’s licence after marrying trainer Rob Waterhouse in 1983, she was met with mistrust from racing authorities. She obtained her Australian Jockey Club licence in 1992, marking the start of her official training career. She trained Gifted Poet, her first winner, and then Te Akau Nick, her first Group 1 winner, shortly after that year.
Gai took over and turned Tulloch Lodge into a powerhouse after Tommy Smith became ill in 1994. She established her status as a generational talent by matching her father’s record of 156 wins in a Sydney season in 2002-03.
Over the years, she won seven Sydney Trainers’ Premierships. She has trained 150+ individual Group 1 winners, and she and Adrian Bott have trained 27 Group 1 winners together.
Gai Waterhouse holds the record for most Golden Slipper wins, with eight. In 2024, Lady of Camelot won the eighth Golden Slipper. This beat her father, T.J. Smith, who had six. She has won the Doncaster Mile seven times, matching her late father, T.J. Smith.
In 2016, Gai Waterhouse and Adrian Bott started a training partnership. They have since formed Gai Waterhouse & Adrian Bott Racing and remained successful together, including Group 1 victories.
‘Who’s who’ of Australian turf legends can be found in a list of horses trained by Gai Waterhouse: Nothin’ Leica Dane, who won the Victoria Derby and famously finished second in the Melbourne Cup a few days earlier; the talented More Joyous; Pierro, who won the Golden Slipper and was a 2YO Triple Crown hero; the tough and determined Grand Armee; and the versatile All Our Mob.
Family Ties: Gai Waterhouse Husband and Children
Rob Waterhouse is more than just Gai’s spouse; he is her strategic partner. Rob, the son of wealthy bookmaker Bill Waterhouse, holds expertise primarily in traditional bookmaking and form analysis. Gai trains champions, but Rob, being involved in the associated businesses, redefined betting with the internet platform, Tom Waterhouse.
Their children, Tom and Kate Waterhouse, have also had successful careers. Respect for one another has been the foundation of their forty-year marriage.
Rob once quipped, “Gai’s the boss—I just cheer from the sidelines.”
Gai Waterhouse Melbourne Cup 2024
No talk about Gai Waterhouse horse trainer, is complete without highlighting her win in “the race that stops a nation.” Fiorente, a horse she trained, raced to victory in the 2013 Melbourne Cup, earning her place in history as the first Australian woman to train a winner. It was one of Gai Waterhouse’s most celebrated Melbourne Cup winners.
Balance Play, Bear On The Loose, Eliyass, Just Fine, Military Mission, New Endeavour, and Poptronic were among the strong candidates her stable, in collaboration with Adrian Bott, offered for the Gai Waterhouse Melbourne Cup 2024 campaign.
Even though Knight’s Choice won the 2024 Cup in the end, Gai’s yearly attack on the Flemington classic is still a top priority, and her desire for more Melbourne Cup success is still burning brightly.
“The Cup is about patience and precision,” she recently told Racing NSW. “We are leaving nothing to chance.”
Gai Waterhouse Daughter’s Wedding: A Personal Victory
Kate Waterhouse married rugby star Luke Ricketson in June 2012 in Taormina, Sicily, Italy. The event, which drew racing royalty and celebrities, will be remembered for the grandeur and class surrounding it. Kate has now established herself as a respected writer, media personality, and novelist. These relationships with family reflect a kinder, more personal side of the dynamic public figure.
The wedding was a pause in Gai’s never-ending schedule. “Family grounds me,” she shared in an interview with Vogue Australia. “Seeing Kate so happy, that’s my greatest win.”

Her recent blog post from the Kentucky Derby in May 2025 reveals her love for the game and her keen observation of global racing patterns.
“Racing is in my blood,” she explains. “I’ll keep pushing boundaries until I can’t.”
