Brilliant sprinter Zoustyle was the star of the day when he gave Gollan his fourth win in the Group 3 George Moore Stakes over 1200 metres.
Gollan also claimed his second Recognition Stakes with Tambo's Mate while Miami Fleiss won the Listed Eureka Stud Classic for a third time for the premier trainer.
Zoustyle was never in doubt leading all the way to maintain his unbeaten record in Queensland with nine wins from as many starts.
Zoustyle smashed the 1000-metre track record in the Swiss Ace Plate at the Sunshine Coast at his previous start and Gollan is now hoping the gelding can gain a wildcard entry into the Magic Millions at the Gold Coast next month.
"He's a hell of a sprinter and he relaxes so well in the middle stages of his races," Gollan said.
"He broke the track record off that long layoff at the Sunny Coast and I always worry about those ratings peak when they produce that sort of run, then backing them up 14 days later.
"His aim is to get a wildcard into the Magic Millions Snippets now."
Gollan, a winner of eight Brisbane premierships, has dominated summer carnivals in recent years.
It was a case of third time lucky for Gollan when Tambo's Mate claimed the Listed Recognition Stakes over 1350 metres.
The Recognition Stakes was postponed from the Gold Coast last Saturday and again at Doomben on Wednesday due to the big wet.
Gollan sent Tambo's Mate to Sydney after the Gold Coast meeting was in doubt and the six-year-old put in a brave performance to finish third in the Listed Starlight Stakes at Rosehill.
"I suppose it was a case of three times proves but I never had any doubt about him backing up," Gollan said.
"He's a really tough horse and tries so hard."
It was Tambo's Mate third win in six starts for Gollan and second Stakes win since being transferred from Caloundra trainer Stu Kendrick.
