The top-ranked Bloods already had the minor premiership in the bag, but wanted to keep their winning streak going, making it 10 victories in a row with a 44-38 win against Waaia.
As a result, the Bloods are destined for a grand final rematch in a qualifying final against the Deniliquin Rovers in a fortnight's time, with the winner headed to a preliminary final once again.
The reigning premier Rovers also hit finals with a win, taking down Yarroweyah by 34 goals in an impressive display.
The 57-23 rout was their second consecutive win and they will be confident of producing an upset against the Bloods in a fortnight, having beaten them by four goals back in round seven.
Katamatite locked up second on the ladder with a comfortable win, taking care of Blighty by 23 goals.
In a perfect response to last weekend's five-goal loss to Katunga, the Tigers controlled most of the game and came away with a 56-33 to book in a qualifying final rematch against the Swans.
Katunga also closed the regular season with a good win, too strong for Mathoura 58-20 in moving to four straight wins.
Elsewhere, Rennie snuck into finals, despite an 18-goal loss to Strathmerton in round 18.
The Hoppers were no match for the fifth-placed Bulldogs, but kept eighth as Picola United beat ninth-ranked Berrigan by 45 goals, finishing with a five per cent edge.
As a result, the Hoppers will face Strathmerton again next weekend, determined to eat into the 18-goal deficit and keep their season alive.
United will face Waaia in the other elimination final, with a fierce game expected after the Bombers won a 54-41 thriller back in round nine.
