Sir Delius had won the Underwood Stakes at Caulfield and the Turnbull Stakes at Flemington and was considered one of the leading fancies for both races.
The entire returned in the autumn to win his 'Grand Final' the Queen Elizabeth Stakes (2000m) at Randwick after placings in the Verry Elleegant Stakes and Ranvet Stakes.
It's a similar program in Melbourne this spring, with Saturday's 1600m contest to be followed by the Turnbull Stakes (2000m) at Flemington on October 3 and then the Cox Plate (2000m) three weeks later.
Waterhouse said to win the autumn 'Grand Final' was a marvellous feat.
"(Jockey) Craig (Williams), Adrian and I had discussed different ways of riding him and I can be a bit vocal about those things, but we got what we wanted," Waterhouse said.
"It was the big prize that we were heading for.
"We live the dream and that's why we come every year, so hopefully the dream will be the Cox Plate this year.
"It's interesting that it is at Flemington this year. It will definitely suit this horse."
