Danglissa Girl has posted a milestone win for Tony Gollan, giving Brisbane's premier trainer the new metropolitan record.

Gollan equalled the late Bruce McLachlan on 78 when Most Important won at the Sunshine Coast on Saturday and set the new standard with Danglissa Girl's Doomben victory a day later.

McLachlan posted his total in 1987/88.

Danglissa Girl was ridden by Brisbane's soon-to-be crowned premier jockey Jim Byrne to a decisive win in a 1200m-maiden for two-year-olds.

The filly by leading first season sire Hinchinbrook out of 1999 Flight Stakes winner Danglissa won her race by 1-1/4 lengths.

"It's a great effort from Tony. He's only a young trainer and he's won a second premiership," Byrne told Sky Thoroughbred Central.

"I rode for Bruce for a long time and I've been riding for Tony this season."

Gollan is on an overseas holiday and is expected back next week.
