The winter carnival is in full swing but Gai Waterhouse is already looking to the spring with Canterbury winner Festivity.

Waterhouse said the filly was a potential Group One winner, nominating the Flight Stakes in October as the target.

Festivity backed up her 1250m win at Canterbury on May 14 with a strong performance over 1580m on Wednesday to underline her potential.

"She is a filly who can go on with it and the Flight Stakes is a race we can aim at," Waterhouse said.

"She has shown today she can run a mile. It was a big effort because she was wide most of the way.

"I don't know what we will do next. We may send her for a spell and get her ready for the fillies races in the spring leading up to the Flight Stakes.

"She has a lovely disposition and a strong hindquarter and all the attributes you need to be a Group One performer."

Festivity was ridden by Blake Shinn who also steered Spice Of Life to victory for trainer-of-the-moment David Vandyke and owner Nick Moraitis.

Vandyke made the trip from Queensland where he has been overseeing the preparation of Saturday's Oaks favourite Arabian Gold who races in the Moraitis pink, white and grey colours made famous by Might And Power.

Spice Of Life prevailed by a short half head over Rapa Nui in a tight finish to the TAB Quaddie Handicap (1900m).

The three-year-old gelding by the Moraitis-owned Power Of Destiny has now won four of his six starts and finished third at his other two.

"I was always waiting to get him up to a trip, and he ran the 1900 metres right out today," Vandyke said.

The trainer said all reports about Arabian Gold remained positive after a scare on Tuesday when the filly pulled off a shoe and narrowly avoided nails going into her foot.

"She was still able to work and is fine," he said.

Arabian Gold has eased from $2 to $2.50 to give Vandyke his first Group One win on Saturday.
