The Raiders were far too strong for Shepparton Lawn Blues, winning nine sets to two, 73 games to 55.
The result comes after the Blues went undefeated in the regular season, only losing to Numurkah in the semi-final.
This semi-final victory was a similar margin to the grand final and forced Shepparton Lawn Blues to take the long route to the big dance.
Numurkah Raiders captain Caitlyn Price said it was a good feeling to take out the title.
“We got off to a really good start, the men didn’t lose a set prior to the mixed which really helped put us ahead before the final matches and it was just a really good team effort,” Price said.
“They were certainly undefeated, probably the toughest side in the comp in the home and away season.
“We just went in with what we thought was our strongest combinations, we’d obviously beaten them a couple of weeks before the grand final as well, so we didn't want to change things to much.
“It just come together for us on the day I guess.”
Price made note of the performance of Jai Harrington, who won his three sets on the day.
She said the win was a team effort and acknowledged Lucy Bassett and Liam Williams for their commitment to the side.
“They travelled across from Yarrawonga each and every week to join our team, so it was great to have them amongst the Numurkah Raiders this season,” she said.
“But when you only lose two sets for the day it’s really hard to pick one person that’s stood out because everyone certainly played their role.”
