With 15 players unavailable across the club's four sides, Tongala's division one representatives knew they had to stand up if they were to come away with the points.
And they certainly delivered winning all three rinks to storm to 72 shots to 55 win.
“It's a terrific result on Moama's greens,” club president Greg Lyon said.
“Winning the opening game of the season means everything to us especially when we did have our backs up against the wall.
“Going forward winning this game will give us a lot of confidence against all the teams in the competition.
“Now we have to beat the lower ranked sides to prove it wasn't a one off.”
Rich River's division one team also got their season off to the perfect start with a narrow 65 shots to 60 victory over Mathoura away from home.
After losing the first rink, the visitors won the next two to start on the front foot.
Elsewhere, City of Echuca claimed a monster 92-48 win over Deniliquin RSL away from home.
The rink of Geoff Beattie, Dennis Compton, John Dinsdale and Steve McCartney were biggest winners by 17 shots.
