"If she could run third or fourth on Saturday, it would be amazing," Perry said.
"It was a good run in the Tea Rose [for 10th] and we were very happy with her. She's going to take a fair bit of improvement out of that run. Physically, she's well ahead of Sofia Rosa at the same stage. This filly is a lot stronger.
"We'd like to see her find two or three lengths on her last run which hopefully would see her somewhere there. We'll be struggling to beat Miss Fabulass but hopefully this can set her for later on.
"We think this trip will be the making of her and she is going really well. Hopefully we have a better horse from this going ahead."
Although Sofia Rosa was turned out after the Flight Stakes, Perry said Santa Catarina could continue her spring back home in New Zealand with a possible tilt at the group three Partners Life Soliloquy Stakes (1400m) at Ellerslie on October 27 and the group one gavelhouse.com 1000 Guineas (1600m) at Riccarton on November 17.
Peaceful's spring aim is the group one Thousand Guineas (1600m) at Caulfield on October 13, though she was this week nominated for the group one Victorian Oaks (2500m) at Flemington on November 8.
"She's great. It's hard to get a line on the Melbourne fillies but Murray and Andrew rate her highly," Perry said.
"I'd like to think she can be thereabouts on Sunday. It's just whether she's forward enough to beat some fairly well-performed fillies. But I'd like to think she's capable of running first or second."
