An entertaining clash for the neutral seemed on the cards throughout the first period, as the two sides largely went goal for goal in the opening 15 minutes.
Tongala edged the opening quarter 14-10 and the Blues only improved after the first interval as they took control of the contest from then on.
Consecutive goals for Moama had it only down 21-15 after 25 minutes before the hosts closed the half strongly, netting seven of the last 10 to take a 28-18 lead into the main break.
The opening 10 minutes of the third period were much tighter as the sides went goal for goal before Tonny again closed better.
Abby Pettifer’s side scored six of the last seven to hold a commanding 39-25 entering the fourth quarter.
Tongala saved its best attacking output for the final period with 16 goals and secured the four points with a burst to start the quarter, scoring eight of the first nine goals.
Moama only mustered seven goals in the fourth term as it was largely shut out in the second half, which the Blues won 27-14.
That set up a comfortable 55-32 win for the hosts, who were powered by 33 goals from Milly Brock.
Tongala (11-4) sits four points ahead of Rumbalara and Moama in third, though Rumba and the Magpies each have a game in hand on the Blues.
Pettifer’s side travels to take on Deniliquin next, the Rams currently locked in a battle to retain the last finals spot ahead of Numurkah.
