A debut Bendigo win has reaped rewards for the connections of If Not Now When.

The Henry Dwyer-trained filly took out the VOBIS Gold Rush on Saturday, giving her owners a $137,500 pay day.

The ownership group of If Not Now When paid just $15,000 for the daughter of Artie Schiller.

"She was a very small filly and still is," Dwyer said.

"We broke her in late because she was so small.

"She's been in work for five months and just had a little break in the middle, but not much."

Ridden by Michael Dee, If Not Know When ($15) scored a three-quarter length win from Launched ($7) with the favourite Valliano ($3) a length away third.

Dwyer described If Not Know When as a real professional, pleasing in all of her gallops, jump-outs and barrier trials have been good.

And now Dwyer can plan her future.

"We don't have to do much from here being a $15,000 purchase," he said.

"It's all upside."
