Ganmain-Grong Grong-Matong ensured they will enter finals in winning form after a 76-point win over Leeton-Whitton on Saturday.
The Lions proved way too good for an undermanned Crows outfit, winning 16.15 (111) to 4.11 (35) at Leeton Showground.
GGGM midfielders Lachie Parker, Aaron Proctor, Tom Anderson and Jesse Lander shone, while Jethro Peck kicked four goals.
GGGM coach Christin Macri was happy to finish the home and away season with a win and will now turn his attention to an elimination final against Mangoplah-Cookardinia United-Eastlakes.
"Our aim was to play well and finish the season off with some good form going into finals so I was pleased to have a 12-goal win and tick that box," Macri said.
"We're looking forward to finals in a couple of weeks. We've got a week to get over sore sports and get right for the first week."
The Lions got through the game unscathed and should have virtually a full list to choose from in the first week of finals with Matt Knagge the only player in some doubt with a hamstring injury.
Tom Van Buuren and Josh Thomas were Leeton-Whitton's best on a tough day.
