Ovens and Murray water polo juniors made the association proud on the weekend, with four teams claiming medals at the Tri State Championships in Geelong.
Pirates' under-16 girls and Sharks' under-14 boys and girls all came home champions, while Sharks' under-16 boys took out silver.
Mixed teams of Pirates, Albury and Northside players came fourth in the under-14 girls and boys.
The border sides came up against players from around Victoria, with many based in metropolitan areas.
Pirates' under-16 girls' coach Kristy Hogan saw her side undefeated throughout the weekend.
"It was an amazing result," she said.
"It just shows the depth of our local kids, especially up against city kids.
"It was a great experience for all of our younger kids and a great result for Ovens and Murray water polo."
Many of the youngsters are now in training for a NSW state event to be held in Sydney in six weeks.
The Pirates' under-16 girls' team are no strangers to success, with many of them playing off for a bronze medal at nationals last year.

"We're really happy because water polo is their number one sport," Hogan said.
"We normally lose them to football or netball, but these bunch of girls are really focused on water polo and want to experience everything they can.
"We're very lucky to have coaches that help out and parents who are so dedicated."
Two rounds remain in Ovens and Murray water polo before finals commence.
