Victory in a restricted race at Rosehill is commonplace for Chris Waller but his experiences of the past few days have reminded him to treasure every win.

Sydney's premier trainer has just returned from a short visit to Ballydoyle in Ireland, spending time with champion Irish trainer Aidan O'Brien and the Magnier family.

Saigon Tea scored a dominant 1-3/4 length win over Medcaut in Saturday's benchmark 85 (1800m) which came as a relief after Waller missed out in the previous race despite having five of the eight runners.

"What I have seen in the past few days has been very special," Waller said.

"Aidan has won 250 Group One races around the worked and it taught me that I can take my ability as a trainer to a whole new level.

"And Saigon Tea's win makes me realise how much I love racing and how lucky I am to be doing what I am doing."

Saigon Tea came to her race with three placings from her previous three starts and Waller said she would probably now be rested.

Also resting at the moment is Cox Plate winner Adelaide who will be prepared by Waller for autumn Group One racing after winning the weight-for-age championship for O'Brien.

"Aidan taught me a lot about Adelaide," Waller said.

"They film all their trackwork which I watched and it told me what to expect.

"They have all his blood profiles and heart pictures. Aidan told me about his idiosyncrasies which will help.

"It showed me the capabilities of how good he is."

Adelaide will be aimed at the Queen Elizabeth Stakes in April and is likely to have one lead-up run.

The Ballydoyle property is the racing arm of the Magniers' global Coolmore operation which incorporates studs in both hemispheres.

The world's other racing powerhouse, Sheikh Mohammed's Godolphin, enjoyed a winning double at Rosehill with Auberge and Vashka.

Godolphin's No.1 trainer in Australia, John O'Shea, has welcomed 13 winners in the past three weeks.

Auberge won the 2400-metre race on the program while Vashka brought up his third win this campaign with a dominant 1300m victory.
