The sport's governing body, Swimming Tasmania, said that the club had created a positive and flexible environment in which young swimmers can thrive.

"With the support of head coach and 2018-19 Tasmanian coach of the year Peter Tonkin, LAC has grown its membership, fostered a supportive culture among both swimmers and volunteers, implemented new processes to improve club systems and embraced development opportunities," it said.

Tonkin said the award recognised the club's ability to work as a cohesive team.

"By working as a cohesive team we have made success inevitable," he said on Facebook.

"Success can be measured by how much the kids enjoy their swimming and by how much each swimmer improves.

"I look back on my early club days as being some of the happiest days in my life. I got lapped in my first ever race but I received a lot of encouragement so I stuck at it. I think everyone deserves a jelly bean."

Hobart Aquatic won the jubilee shield for the most success at Tasmanian championship events.
