When it comes to the cut-throat business of jockeys chasing better rides, Chris Waller insists there is no difference between Sydney and Hong Kong.

Back in town after overseeing Preferment's unsuccessful Hong Kong Vase campaign, Waller will rely mostly on two young ex-kiwi jockeys to do the stable's riding at Rosehill on Saturday.

In Jason Collett, Waller is calling on a jockey who confirmed he is making inroads when he rode three winners and a dead-heater at Randwick last week.

Yet even with the backing of Waller it has taken Collett time to gain a foothold and the trainer says the young rider still has a lot more to do to consolidate his new-found popularity with owners.

It's the same with stable apprentice Rory Hutchings who has four Rosehill rides for his boss and is gradually settling into Sydney racing after a slow start since arriving as New Zealand's champion junior rider.

"Rory is starting to get noticed," Waller said.

"Sydney's like Hong Kong. Don't think it's not. If you run seconds and don't win you don't get the next opportunity.

"If you win races the opportunities come."

Waller has three early favourites and the 1.5kg claim of Hutchings will be used on the most interesting of the trio.

Start Wondering was an acceptor for two races but Waller has decided to kick off the former New Zealander's campaign over 1200m in the McGrath Estate Agents Handicap.

At his only start for Waller, Start Wondering made an immediate impression winning over 1350m at Rosehill in August.

It took the five-year-old's record to five wins from nine starts and Waller has no doubt there is more to come.

"He was coming out of moderate form races in New Zealand, but he's just one of those horses which has really adapted to Sydney and Sydney racing," Waller said.

"I think he can get to Group Three level but beyond that it's always a bit unknown."

Waller is hoping he can provide Tommy Berry with a winner on the jockey's first day back in Australia after riding in Japan and Hong Kong over the past five weeks.

Berry is on Cauthen's Power in the TAB More Than Just Winning Handicap while Sam Clipperton has a rare ride for Waller when Chandana tries to make it back-to-back wins in the Hyland Race Colours Handicap.
