Horne also achieved his personal goal of swimming a sub 60sec 100m freestyle, a time that coach Tai Daniela joked means he can now call himself a swimmer. Horne then went sub 59, taking the bronze medal in the final. Horne's fifth and sixth medals, a bronze and silver, came in the 50m and 100m backstroke.
Claudia Capp (15) was twice denied a medal by the closest of margins. Her 100m freestyle time of 1:00.22 was a big personal best for fourth place and she also placed fifth in the 200m freestyle, sixth in the 200m butterfly and seventh in the 800m freestyle.
The GSC freestyle relay team of Capp, Danielle Waiari, Stacy Muir and Hannah Philpot (all 15) came fourth in the final.
Calum Gilmour (15) made two finals in his favoured butterfly disciplines. The pick of his races was a strong sixth place in the 100m butterfly in a personal best 1:02.33. Libby Bradley (14) came ninth over the 50m freestyle in a personal best 28.78s, while Dannielle O'Connor (18) finished seventh in 28.07.
