Swimming WA hosts the Open Water Swimming (OWS) Series, the largest series of open water swimming events in Australia. The OWS Series has become an icon of the Western Australian sporting calendar, attracting amateur and professional swimmers from age nine to ninety-nine.

The series includes 10 events conducted across Perth and regional WA from September to March.

Events start at 500m and span distances all the way up to 10km. While swimmers can use their times to qualify for Nationals and/or record an official placing and score points in the OWS Series, Swimming WA encourages everyone to have a go and be a part of what is sure to be an exciting series.
