Throughout a proud history spanning more than 50 years, the NZB Filly of the Year Series has repeatedly unveiled superstars of the racetrack and the breeding barn. But the 2023-24 edition of the series turned out to be one for the ages, with three different fillies going on to win Group One races during the season and one standout racehorse that could not be caught.

There were six heats at Randwick on Friday morning won by juveniles including some unraced prospects by champion sires including Snitzel.
