Ganmain-Grong Grong-Matong opened the season with 55-point victory over Narrandera on Saturday.
The Lions kicked eight goals to two after the main break to runaway with a comfortable win, 15.17 (107) to 8.4 (52) at Narrandera Sportsground.
GGGM's new-look forward line functioned well with Ben Walsh and Jack McCaig kicking four goals each, while Jethro Peck and Jacob Anderson also contributed two each.
GGGM coach Christin Macri was happy with the way his team got their game going in the second half.
"It was a tight first half but we tidied a few things up at half-time which allowed us to get on top in the second half," Macri said.
"Obviously you want to win to start any season and once we started to tidy up a few things, it went from there."
It was the Lions leaders who led the way, with Ben Walsh and Jacob Olsson best for GGGM. Michael Rothnie impressed in his first game for the club.
Connor Vearing, Harry Grintell and Corey Baxter were among Narrandera's best.
