Dual New Zealand Group One winner Say No More makes her Australian debut on Saturday as trainer Paul Duncan looks to kick-start a new phase of his career.

Duncan moved from New Zealand to set up a new base on the Sunshine Coast in June.

Say No More, who runs in a 1350m fillies and mares handicap at Doomben, is being aimed at the Myer Classic in Melbourne this spring.

The five-year-old won the Group One Thorndon Mile (1600m) in January and the Group One NZ Thoroughbred Breeders Stakes (1600m) in April.

"Her aim is the Myer Classic in Melbourne so this is a starting point for her," Duncan said.

"I know she's got to carry a lot of weight which is not ideal but I want to start her off here and make sure all is well and then she can go interstate."

Say No More's two big race successes this year took Duncan's Group One tally as a trainer to four after wins to Oarsman in the 2003 Wellington Cup and Midnight Oil's New Zealand Oaks win last year.

Duncan said he trained between 20-25 horses when based in New Zealand at Cambridge and now has eight horses in his care at Caloundra.

"It was something I wanted to do for a while, to give it a go over here in Australia," he said.

Say No More had a two-month spell after winning her second Group One on April 7 at Te Aroha before heading to Queensland.

"She arrived in the first week of June and it's been a nice slow build-up," the trainer said.

"She looks well and has thrived up here."

The trainer has pencilled in the Angst Stakes in Sydney for Say No More's next start but said those plans could change depending on Saturday's performance.
