Dunn also received $2000 for his victory, and could not resist a dig at the older drivers before he left.
"Maybe the old fellas might want to bring their glasses next year so they can see out there and go a bit better. It might be walking sticks by then, too."
Dunn was consistent throughout the five races, gaining a second and a third along with his fourth in the last race, and opening up the series with a win behind Veecewah.
The Red River Hanover mare was having just her second start back as a pacer after 31 starts as a trotter.
Trainer Alex Milne of Edendale was pleased for his son Grant, who owns the 8-year-old and has done a lot of the work with the mare at Forbury Park since she returned to pacing in the past few weeks.
"I reckoned she was good enough to win as a trotter and she had done that and after that, she didn't really want to trot early," Milne said.
"So the last resort, it was back to the hopples."
Veecewah started her career pacing, and climbed through the grades with three wins in the 2010-11 season, before struggling in the C3 grade. "The trotting might have done her some good, though - it's given her a chance to get used to racing without the pressure," Milne said.
