Jimboomba State School students battled it out in the pool from November 26-29 at the annual swimming carnival.
The year ones and twos dived in on November 26.
Years three and four made a splash on November 28 and grades five and six hit the blocks on November 29.
Students competed in age races, a fun tyre tube race and the carnival wrapped up with all of the excitement of the traditional students versus teachers event.
Logan house won the overall championship with 825 points, ahead of Flinders on 751, Henderson (750) and Lindesay (664).
Standout performers included 10-year-old Tiahme Langley who powered through the 25 metre freestyle in a time of 15.66 seconds to smash the record.
It was also a red letter day for 11-year-old Ryan Sutcliffe.
It seemed like every time the gun fired, Sutcliffe was setting a new benchmark.
He finished the day with four records to his name after dominating the 50 metre freestyle and backstoke, the 25 metre freestyle and the 100 metre individual medley.
