New Zealand's premier stable will be reduced to satellite status with trainer John Sargent planning to train full-time in Australia.

As he prepares Choisir colt Good Job Bro for an all-or-nothing Golden Slipper bid at Warwick Farm on Saturday, Sargent has revealed he has finalised plans to transpose his trans-Tasman training operation.

"I'll be moving full-time to Australia in a couple of months," Sargent told AAP.

"It will be a good challenge but if you think you know your job you may as well go where the money is."

"There's good money here and it is getting tougher at home."

Sargent opened a Warwick Farm stable with limited numbers at the start of the 2012-2013 racing season.

As he had planned, Sargent confirmed his Matamata base, which produced a New Zealand record 111 winners last season, would become a feeder stable for his Australian operation.

"I won't be closing the New Zealand stable down," he said. "I'll get a lot of the young horses up and going over there because it works out cheaper."

Sargent has been active in the yearling sales market and he is preparing a campaign to syndicate his 2013 purchases.

On the racetrack, the first nine months of his foray into Sydney racing have been highlighted by a sequence of wins with Cathay Lady and the emergence of Good Job Bro as a possible Golden Slipper horse.

Cathay Lady earned black type with a Gosford win before a short break.

She returns on Saturday but her appearance will be overshadowed by her younger stablemate.

Good Job Bro will take his place in the $125,000 Group Three Skyline Stakes, a race which earns the winner ballot-free entry into the Golden Slipper.

Cathay Lady resumes with a rider change in the Listed Wenona Girl Handicap after a nine-week break since winning in the same grade in the Belle Of The Turf at Gosford.

Black Shinn was declared at acceptance time but Sargent said Brett Prebble, in town to ride Ferlax in the Randwick Guineas, would have the mount.
