The two Mater Dei teams took all before them at the Southern NSW finals at Lavington Sportsground on Wednesday.

Both teams showed plenty of character in producing come-from-behind wins.

The boys made the most of their opportunities to defeat Albury Public School 2.2 (14) to 0.7 (7) in the final.

The girls produced a big second half to down Griffith East 4.6 (30) to 2.4 (16) in their final.

Mater Dei teacher and girls coach Steve Carroll said the school was proud of both teams' efforts.

"I don't think we've ever had two go through together before," Carroll said.

"They both did well because it was tough competition.

"The boys beat Albury Public in the final, who had beaten them earlier in the day. They were down in the final and kicked two late goals to win.

"The girls played Griffith East in the final and were down by three points at half-time but they fought back and did well.

"Both teams should go up to the final confident that they will be competitive."

The Mater Dei boys team lost to Albury Public by 25 points in their opening game of the day but bounced back with wins over Hay Public School (28 points) and St Patrick's Primary School (22 points) to make the final.

The girls cruised through to the finals with big wins over Albury Public (38 points), Griffith East (42 points) and Hay Public School (26 points) before being tested the decider.

The state finals will be held in Sydney on August 18.
