Robert Heathcote's decision to switch between states with Buffering has come with an unexpected bonus for the premier Queensland trainer.

Buffering, with six wins in nine starts, will line up as a leading chance in the Governor Macquarie Cup (1200m) at Randwick on Saturday.

It is a Listed race usually known as the Brian Crowley Stakes and since being shifted away from the Sydney carnival spotlight it has provided an unlikely form reference to Buffering's main spring target - the Group One Coolmore Stud Stakes on Victoria Derby day.

The Gai Waterhouse-trained Northern Meteor completed the double in 2008 and last year's winner Love Conquers All was luckless in finishing ninth in the Group One.

Heathcote said he was unaware of the race's recent significance as a Coolmore pointer but wouldn't be surprised if the trend continued.

"The reason why I brought him back to Sydney for the Roman Consul was because I couldn't find suitable lead-up races to the Coolmore in Melbourne," Heathcote said.

"Looking at it now, Saturday's race might have been the right way to go all along.

"It could easily turn out to be the right form race again for the Coolmore because it's a pretty good field."

Buffering was runner-up in stakes races at Warwick Farm and Flemington before returning to Sydney to beat Obsequious in the Roman Consul.

Heathcote says the Darley filly once again represents Buffering's biggest danger.

"I've got a huge amount of respect for her," he said.

"She was going with my horse at the top of the rise (at Randwick) until her condition gave out."

Heathcote will use leading Queensland jockey Glen Colless on Buffering.

Colless was on board when the gelding, owned by a syndicate which includes current and ex-Socceroos stars, scored a first-up win at Eagle Farm in August.

Only seven three-year-olds have accepted for the race after Chris Waller stuck to his midweek decision to save Pressday for a first-up tilt at the Coolmore.

Pressday's non-acceptance has allowed veteran jockey Jim Cassidy to take the ride on Hinchinbrook.

Hinchinbrook, who is also being aimed at the Coolmore, will be trying to get his spring back on track after an interrupted campaign.

Heathcote, meanwhile, is trying to find a positive in Woorim's wide barrier in the Group Three Betfair Stakes at Caulfield.

Woorim, who has been placed at his past two Melbourne starts, will start from gate 10 in a field of 14.

"With Caulfield being a wet track it might be better to be out deep," Heathcote said.
