New Zealand fillies hold sway in the Group Two Doomben Roses following the withdrawal of the early favourite Ballet Suite to concentrate on the Queensland Oaks.

Trainer Chris Waller has decided to save Ballet Suite for the Group One race on Saturday week rather than subject her to a seven-day back-up.

That leaves NZ 1000 Guineas winner and NZ Oaks runner-up Platinum Witness as the $2.40 favourite to claim the first leg of the double famously completed by another kiwi, Ethereal, in 2001 before her Caulfield-Melbourne Cups wins later that year.

The second elect is Bohemian Lily who is having her fourth start for Gai Waterhouse after doing her early racing for Lance Noble across the Tasman.

She is at $3 with Exquisite Jewel the only other runner under double figures at $8.

The Sue Walsh-trained Exquisite Jewel ran fourth in the NZ Oaks in March in which Platinum Witness ran second to Savaria.

She then beat Werther in a 2000m Group Three race before running second to him in the Group Two Championship Stakes (2100m) at Ellerslie.

Werther has since run second to Delicacy in the South Australia Derby ahead of a tilt at the Queensland equivalent.

The Waller-trained Winx, winner of last Saturday's Sunshine Coast Guineas, is the $2.25 favourite for the Queensland Oaks ahead of Ballet Suite at $7 with Bohemian Lily and Platinum Witness at $9.

Exquisite Jewel is a $21 chance in the Oaks.

The last horse to complete the roses-Oaks double was another New Zealander, the Graeme Rogerson-trained Scarlett Lady in 2011.
