In the club relays, the quartet of Bianca, Skye Cox, Kapua Warbrick and Milla gave it everything to come 10th in the 4 x 100m freestyle. Bianca, Skye and Milla then combined with Annelyse to pick up 8th spot in the 4 x 100m medley relay.
Head coach Alastair Johnson was pleased with the team's efforts.
"We have enjoyed a very good week. Our goal was to break into the top 10 teams, and were just outside that with a national placing of 14th. We are still a young team and I am very confident that we will come back next year with a bigger and faster team to crack that top 10 place."
