Andrew Noblet is poised to have Group One chances in different states on the same day with his stable stars Super Cash and Silent Sedition.

Noblet came close to a first Group One win when Silent Sedition ran second in last year's Australasian Oaks - his most recent starter at the elite level.

Super Cash earned a crack at Saturday's Newmarket Handicap at Flemington with her first-up win in the Group Two Rubiton Stakes, while last-start Mannerism Stakes winner Silent Sedition has Saturday's Coolmore Classic at Rosehill as her target.

Melbourne's leading apprentice Ben Allen has been called on to ride Super Cash, who has 52kg, after Katelyn Mallyon failed in her appeal on Tuesday against a careless riding ban.

"It's very bad luck for Katelyn," Noblet said.

"She has done a lot of work on the horse this time around."

Allen rode Super Cash in trackwork on Tuesday and Noblet said he had been impressed by the apprentice's recent riding.

Noblet has been keen to get Super Cash to the Newmarket given she has raced well down the straight.

He was delighted with how the mare went in a jump-out at Caulfield last week and by her work on Tuesday in preparation for the Newmarket.

"She had to run right up to them in the Rubiton (to have a crack at the Newmarket) and she did that really well," he said.

"This is the next step with her. We didn't run her in the Oakleigh Plate on purpose just to have her spot-on for this. She's in great order."

Silent Sedition travels to Sydney overnight on Thursday and Hong Kong-based Sam Clipperton, who won the Coolmore Classic last year on Peeping, has the ride.

"It will be interesting to see how the track is by the end of the week because she has never been on a wet track before which is one question mark," Noblet said.

Silent Sedition will also be racing in the clockwise direction for the first time, although Noblet said she was pretty adaptable and seemed to get around that way well in recent trackwork gallops.

"Her two runs this time in have been really good. She has come on since her last start and going to 1500 metres won't be a problem," he said.

"It's a good race but she never runs a bad race and she deserves a crack at this. She'll run well."
