Numurkah earned the opportunity to defend its Goulburn Murray Lawn Tennis Association GM1 title after an epic weekend on the courts.
The Warriors won through to the decider with a 6-72 to 4-49 result against the Shepparton Hornets, who the Shepparton Lakers then beat in Sunday's preliminary final to book their spot in the grand final.
The Warriors were clinical in their semi-final win against the Hornets, winning six of the match's 10 sets with Mark Mills and Helene Steward each turning in 3-0 days to lead the side.
For the Hornets, James Curtis-McDonald and Kyle Andrew each produced two set wins, but it was not enough to avoid cashing in the team's double-chance for a preliminary final berth.
They met the Lakers once there, after they won a thrilling contest against the Shepparton Bulls by just eight games.
In winning 68-60 with six of the 10 sets, the Lakers would have been thankful for big wins from Kate Durling, who won her singles 8-2 and her doubles (with Katie Ferguson) 8-2 to give her side the games advantage.
Sunday's preliminary final brought another tight contest; the Lakers and Hornets split the 10 sets, but the former took the grand final position with 59-52.
Durling was again an MVP candidate, winning her three sets with a 15-game advantage to the Lakers, while Luke Dixon also pinched two of his three sets.
Giselle Andrews battled hard for the Hornets, winning her singles match 8-1 against Katie Ferguson.
● GM2 is destined for a Shepparton derby grand final, with the Lions to battle the Saints for the premiership.
The teams met in Saturday's semi-final, but it was one-way traffic, the Lions winning 10 of 11 sets in a 77-36 demolition.
The Saints will need to come up with a big improvement to match it with them this weekend, although they did show some signs of lifting in their preliminary final win against Numurkah.
They earned a 14-game advantage with six of the match's five sets to earn their rematch next weekend.
● GM3 East's decider will be between Tatura and Nathalia, GM3 West's will be between Tatura and LBU, while GM3 Open's will have Kyabram and Tongala square off.
