Darley's high-profile three-year-olds Epaulette and Albrecht will be kept apart during the autumn to chase Group One Guineas success in two states.
Albrecht, who was denied by stablemate Epaulette in a one-two Darley finish to the Group One Golden Rose in September, is being readied for an early 2013 campaign in Melbourne while Epaulette will be kept for the Sydney carnival.
"Albrecht is in work and he'll go to Melbourne in probably another six or seven weeks and I'll aim him at the races towards the Australian Guineas third-up," trainer Peter Snowden said.
The Group One Australian Guineas (1600m) at Flemington is on March 2.
Albrecht, a son of Redoute's Choice out of a full-sister to Lonhro, has won two of his five starts including the Group Three Up And Coming Stakes (1300m) with seconds in the Golden Rose and Group Two Stan Fox Stakes.
Epaulette continued on to Melbourne after his Golden Rose triumph and won the Caulfield Guineas Prelude before running third to All Too Hard and Pierro in the Caulfield Guineas.
"Epaulette will stay here in Sydney and race in the races leading up to the Randwick Guineas," Snowden said.
Fellow three-year-old Academus returns home from Perth on Wednesday having taken out the Group Two WA Guineas (1600m) last Saturday.
He'll have a decent spell while veteran sprinter Pinwheel also returns from Perth but will only have a short break.
Pinwheel ran on for fourth in last Saturday's Group One Winterbottom Stakes (1200m).
"Pinwheel will just have a couple of weeks off and I'll kick him back off in the Group Two weight-for-age Australia Stakes in late January at this stage," Snowden said.
"Two weeks after that is the Group One C F Orr Stakes over 1400 metres."
Snowden is hoping residual fitness can play a role in the Orr Stakes on February 9.
"It's a Group One and it's just a bit before everything is really wound up. And he'll be in good order then," Snowden said.
"Then I'll give him a breather and head towards the Stradbroke."
