After winning the toss, Hilton-Palmyra elected to bat first, taking advantage of the beautiful weather.
They got off to a flyer, scoring 230 runs for the loss of just eight wickets, with middle-order batsman Phil Holman scoring a game-high 70 points, supported by team-mate Jeremy Vlasich with 65 runs, with Vlasich eventually taking out man-of-the-match honours.
Confident of a win, East Fremantle took the bat, but floundered early, eventually being all out for just 191 runs.
Hilton-Palmyra’s Samuel Collins was the pick of the bowlers, taking three wickets.
The win was Hilton-Palmyra’s 11th first-grade premiership and the first since 2004.
