The Lake Leschenaultia Open Water Swim is held at Lake Leschenaultia, Chidlow in the Perth Hills on the 2nd Sunday of November. The 2019 event being held on the 10th November is the 33rd Anniversary of this event.

The event is swum in a freshwater lake and doesn’t present any danger to swimmers except for friendly ducks and the occasional inquisitive long-neck turtle.

There are four distance swims as well as a children’s race at the end of the 4 main events.

Prizes are awarded to the 1st, 2nd & 3rd Female and Male Swimmers, Spot prizes randomly presented to other competitors and bags of lollies given to all children entered in the Children’s Swim.


The Lake OWS is comprised of four swims; the first the 400m “Go Jump in the Lake” swim, specifically targeting novice swimmers or those who would like to swim but are not confident or able to swim a longer distance

This will be followed by 800m, 1600m and 3200m swims.

There will be a separate 400m course which will be used for both the 400m & 800m events with a second course of 800m assigned to the 1600m and 3200m events.

Following the completion of the main events, we run one mini OWS (Minnows swim) for the children of competitors, friends and visitors
