As he streaks to a third Sydney premiership with a training record in hand, Chris Waller says he will make a few changes next season - but not too many.

Waller celebrated yet another milestone in his career on Saturday when Oompa Loompa gave him the win he needed to pass the standard of 156 Sydney winners in a season jointly held by TJ Smith (1975-76) and Gai Waterhouse (2002-03).

After another three winners on the day at Rosehill, Waller is on 159-1/2 with seven meetings left for the season.

With 10 fewer city meetings for 2013-14, he will set a mark that is unlikely to be bettered, even by himself.

He deflects credit for his success to his staff and the systems in place at his Rosehill stable but he is very much the captain of the ship.

That comes at a cost and Waller admits his wife Stephanie and his two young children are the ones who miss out.

"I don't plan to do a lot differently," Waller said. "I just want to take a step back and spend a bit more time at home and keep about five per cent of my time for other things."

Waller's other three winners on Saturday were Fulgur, Eigelstein and Secessio, all tried horses sourced from Europe, a plan the trainer formulated when he was building his stable because he couldn't afford to buy yearlings in Australia.

The annual Tattersalls Sale has now become a drawcard for Australians and the prices have gone up with Waller increasingly turning to the German market where he found Secessio and Eigelstein.

This season Waller has also expanded his horizons to include a Melbourne stable with room for 20 horses.

"We will continue to train the horses out of Sydney but it gives us options to send them to Melbourne and helps prevent having multiple runners in races," Waller said.

"That benefits the owners."

And although he is justifiably proud of the new record, perhaps Waller's biggest achievement over the past year is that he is the country's leading Group One trainer with nine victories at the elite level with eight different horses.

He has come a long way from the small town of Foxton on New Zealand's North Island where the biggest name in racing used to be Castletown, a multiple Group One winning stayer who ran third in the 1992 Melbourne Cup.

Castletown was trained by Waller's mentor Paddy Busuttin and the horse was so popular they named a motel in Foxton after him.

Waller's success is such they may even name a road after him.
