Tony Gollan has equalled his best Brisbane metropolitan training effort with four winners at Doomben and hopes his luck will continue with his application to get Sydney stables.

Gollan combined with jockey Jim Byrne for all four winners on Wednesday and it lifted Byrne back into the premiership race, leaving him 2.5 winners behind Jeff Lloyd.

Gollan has applied to the Australian Turf Club for the 30 boxes at Rosehill to be vacated when trainer Michael Freedman moves to Randwick.

He said reports he had been granted the stables were premature but he hoped to get a decision in the next week and be ready to start in August.

"There is nothing official yet and I don't want to jump the gun before officials make a decision. I indicated I wanted to have a Sydney presence at the end of last season and we have been working on it for a year," Gollan said.

"I would be honoured to get Sydney boxes but will be maintaining my stables in Brisbane at full strength."

Gollan said many of his owners had horses eligible for the NSW BOBS bonus system and wanted runners in Sydney.

The premier Brisbane trainer and Byrne combined at Doomben to win with Irish Bandit ($3), Dame Van Winkle ($3.50), Brazen Moss ($2.70) and Shipwrecked ($2.30) to give him 84.5 metropolitan winners for the season and 103.5 overall.

The quartet equalled Gollan's previous best training effort when he won four races at the track in April 2015.

Byrne moved to 69.5 wins for the season and did his best for a fifth winner when he finished second on Hi I'm Back and protested unsuccessfully against Tiffani Brooker on the winner Johnro.

Stewards found while Brooker, who completed her first Doomben double on Johnro, had impeded Byrne's whip action it had not been totally her fault.

Brooker had earlier won on Cobarchie ($4.80) for Johnro's trainer Paul Duncan who has several horses for owner Greg Ingham.

Lloyd won on first starter Five Stud Poker ($3.20) for trainer Rob Heathcote who is also having a good run getting his 60th winner for the season.

"Five Card Stud was bred at Dato Tan Chin Nam's Think Big Stud and is a full brother to the good horse I had for him, Gid Up Strop," Heathcote said.

"We lease Five Card Stud from Dato and it is always good to get a winner by his sire Pendragon."
