Winx is to be immortalised with a statue at Rosehill as preparations get underway for her final campaign.

Trainer Chris Waller and the champion's owners have announced plans for the autumn, but have also advised the mare will be immediately retired if they don't believe she is at her best.

The winner of 22 Group One races, Winx will be the second horse to be honoured with a statue at Rosehill with inaugural Golden Slipper winner Todman the other.

The Australian Turf Club will discuss the project with Winx's connections and is also planning to honour her on each of the four days she is scheduled to race.

"Whenever Winx races, Royal Randwick and Rosehill Gardens will be covered in a sea of blue colour with Winx flags, special merchandise on sale and Winx Farewell Tour pins," the ATC said.

"The Australian Turf Club will also begin consultation with the owners of Winx and trainer Chris Waller for plans to build a statue of Winx at her home course Rosehill Gardens to forever celebrate her remarkable career."

ATC chief executive Jamie Barkley said Sydney fans were set for more rare moments in Australian racing history.

"We are thrilled and grateful to Winx, her owners and trainer Chris Waller for giving Sydney an opportunity to see her live on course for another campaign," Barkley said.

"Winx is a once in a lifetime horse and the Australian Turf Club will be throwing everything at promoting racing for all of Sydney to enjoy and celebrate her runs.

"We are especially excited to begin plans for a statue of Winx at her home track at Rosehill Gardens."

Winx's likely autumn campaign will begin with the Group Two Apollo Stakes on February 16 followed by her attempt to win the Group One treble of the Chipping Norton (March 2), George Ryder (March 23) and Queen Elizabeth Stakes (April 13) for a third time.
