Penshurst took out the first of nine Mininera District grand finals at Alexandra Oval on Saturday.
The Bombers were too good for Moyston-Willaura, winning 27-18 in the 13-and-under netball decider.
They dominated for much of the contest, preventing the Pumas from any opportunity to claw their way back into the game.
Penshurst’s Alexandra Page won the best on court medal.
The 13-and-under game finished just in time, with the rain pouring down shortly after the conclusion of the game.
