Elena Forlong (17) chipped in with a silver and three bronze, while Cayden Earles (11) returned home with two bronze and Amelia Cronin-Townsend (13) a bronze.
Coach Andy McLay said club culture had played a major role in the success.
"The Wellington performances were great to see, every single one of them stood up," McLay said.
"This is hard evidence that the club culture developed here is working to help lift performances throughout the age groups from juniors through to the seniors. The younger one and new members can see it's not only the top swimmers winning everything, it's everyone throughout the club.
"They can see that if others can achieve it in the pool, so can they. This trophy means a lot to the club," he said.
