Four Blues teams are still in the finals, with only one being eliminated from premiership contention last weekend.
Tongala was far too strong for Moama, winning a grand final qualifier between the two local sides by 39 goals.
The Blues were the better side early, opening up an 11-goal advantage by the end of the first period, before doubling down with devastating effect in the remaining three periods.
A 14-goal second quarter saw Tonny lead 33-15 at half-time, and it totally dominated the second half, outscoring Moama 35-14 after the main break to run out as a 68-29 winner.
Goal shooter Meg Brennan was sensational on the day, netting 56 times for the Blues.
Tongala could face the Magpies again in the grand final, though that is dependent on Moama getting past Mulwala in a preliminary match-up this weekend.
C-grade
Tongala won another grand final qualifier against Moama in C-grade, comfortably triumphing 46-28.
Tracey Hughes (24) and Tamara Cummins (22) were the goalscorers as the Blues outscored the Magpies 33-21 after the first period.
C-reserve
In another Tongala-Moama grand final qualifier, it was the Magpies who booked their spot in the big dance in this division, edging the previously undefeated Blues 37-32.
Tonny will now play Rumbalara in a preliminary encounter for the opportunity to set up a rematch on the final day of the season.
17-and-under
Moama defeated Tongala 56-52 in a grand final qualifier, while Echuca United won a second post-season match by edging past Rumbalara 59-57.
As a result, the Blues and Eagles now meet in a preliminary final this weekend.
15-and-under
Echuca United defeated Tongala by four goals in an elimination semi-final.
The Blues led 23-20 going into the final period but couldn’t hold on, falling 31-27.
