Group One winner Silent Sedition will be tested down the Flemington straight course for the first time when she makes her season return in the Gilgai Stakes.

The Group Two 1200m-sprint will be a stepping stone to the mare's main spring goal, the Group One Myer Classic (1600m) at Flemington in November.

Trainer Andrew Noblet is expecting a bold first-up showing.

Silent Sedition broke through at Group One level during her autumn preparation in the William Reid Stakes at Moonee Valley, giving Noblet and jockey Katelyn Mallyon their first elite-level wins.

Either side of the William Reid, Silent Sedition raced in two Group One races in Sydney, finishing a short half head second in the Coolmore Classic and 1-1/4 lengths fourth in the Queen Of The Turf Stakes.

"She looks really good," Noblet said.

"She's in great order and she's ready to go.

"I can't fault her condition and work. Everything is ticking along well so I don't see why her race form would be any different."

Silent Sedition has raced once at Flemington for a Group Three placing last spring over 1400m around a bend.

"The straight would be the only question mark going into the race," Noblet said.

"But she handles everything else well so I can't see why she wouldn't handle it."

Silent Sedition cut a foot while in the spelling paddock which put her back a couple of weeks but Noblet is thrilled with the way she has come back and plans to get her to the Group One Myer Classic at the third run of her campaign with the Tristarc the second.

"Hopefully it all works out," Noblet said.

"She's matured and looks really good. I don't know if she's got any bigger but she's definitely got more muscle mass on her."

Silent Sedition has only missed a top three finish twice from 17 starts and has won six races.

She is on the second line of betting for the Gilgai behind Speith.
