Oliver, who is two months into his return to riding after serving a ban for betting on a rival horse in 2010, thanked Waterhouse for giving him the chance and said he was proud to deliver her a first Melbourne Cup.
"She's done so much for racing. It's a great honor for me to help bring her home her first one,'' Oliver said. "Gai was one of the first people to really get behind me when I came back. I can't thank her enough for helping me get going again.
"We have been a great team together.''
Capturing her first Melbourne Cup reverses what had been an unhappy year for Waterhouse, who was involved in a public dispute with media mogul John Singleton, who fired her on live television as trainer of his horse More Joyous during the Sydney carnival.
That dispute centered on Singleton's belief that Waterhouse's son Tom, a leading bookmaker, was being given information on the horse's condition that he was not. Gai Waterhouse was fined for not keeping stewards fully informed of the horse's fitness.
