Beaudesert Swimming Club held their annual club championships on Friday and Saturday.
Club president Kara Cuskelly said the event was a culmination of the club's season where swimmers vied for the coveted champion title for each age group.
"Swimmers have had a tremendous amount of racing in the past 7 - 8 weeks with club, regionals and state swimming along with school district and regional trials and school state swimming competition taking place this week," Ms Cuskelly said.
"Our swimmers have been working hard and reaping the benefits of their training, posting a myriad of personal bests."
Six-year-old competitor Emma Arkinstall said she was excited to swim and confident of a win.
"I think I will get a trophy anyway because I'm the only six-year-old in it," she said.
Ms Cuskelly said eight records were broken over the weekend by swimmers Ryan Sutcliffe, Sam Blyton, Kierston Cuskelly, Kaleb Browne and Marius Borz.
"Some records were very long standing within the club, in excess of 28 years," she said.
"All swimmers should be incredibly proud of their performances.
"Ryan Sutcliffe had a stellar weekend breaking three of the eight records and will represent the South Coast Schools swimming team at Queensland School States this week in the 4 x 200m free and medley relays along with the 50m freestyle, Back and Fly and 100m Backstroke."
