Senior broke a record in every race she competed in the 13 years girls age group, including one that spans back to 1971 in the 50m breaststoke.

In fact, Senior was so dominant in the pool she swam faster than any girls record the school has across any age group.

Sports organiser Kelly Lawson was very impressed with her efforts.

Senior wasn’t the only one breaking records with 11 broken overall.

Tristan Brown claimed four open records, all previously set by Ryan Robertson in 2007.

Lawson said it was one of the school’s highest participation carnivals ever with almost every student hitting the water to race or take part in a novelty event.

"There was a lot of cool dress ups as well and the senior kids really get involved in a lot of costumes but there was lots of house colours throughout the day too,” Lawson said.

Macarthur won the house competition by over 300 points while students got some revenge over the teachers in the water polo match.
