It will send 20 swimmers to the championships, with many having qualified in multiple strokes and distances.

“I think we’ve probably had roughly 20 (swimmers competing) the past three years, which is good, but in the past, we’ve had guys do only one event or two events,” Warrnambool swimming coach Josh Sobey said.

“It’s pretty exciting to have two under 12 teams: a boys’ team and a girls’ team.”

Swimmers earn the chance to compete in the age championships if they meet a preset qualifying time at meets during the year.

Sobey said there were a number of swimmers in particularly good form, including Robbie Gleeson and Alex Johnston.

From the Warrnambool squad, 14 will compete in individual events, while a further six will take part as relay-only swimmers.

The championships run from December 10-15.
