A grand total of 11 primary-aged students went to Catholic State recently, with Thomas Carey advancing to the PSSA state titles.

Bowning Public School Student Dylan Mann also had a season to remember, attending the state titles to participate in the small schools relay team.

Bush was proud of her charges and what they'd achieved in the 2014/15 season.

"The kids have been training hard and they got the results with heaps of PB's which is good," she told the Tribune.

"I have 80 in the Yass Swim Academy now and I also have a waiting list, so it's good to see such interest in the area."

Most of her young swimmers advanced to regionals at the very least this season.

"To have everyone swim so well across the board is pretty rare and it's great to see."

Along with 11-year-old Thomas Carey and Dylan Mann, there were a number of other notable performers.

Darcey Bush went to Catholic State for the 50m freestyle, butterfly, breaststroke, backstroke and also participated in the relay event.

Alice Henman came fifth in the 50m freestyle, just missing out on state selection, and also swam in the 50m butterfly.

Maya Smith also swam well at Catholic State, participating in the 50m breaststroke event.

Bush said it's a shame the season's over.

"I have state swimmers here and the fact is there's nowhere to train, we'd love an indoor pool.

"Some of the kids might swim a bit in Canberra but other sports sort of take over now anyway."

She said she's already looking forward to a big 2015/16 season.
