South32 Rottnest Channel Swim 2026

One of Australia’s iconic community sporting events and the largest open water swim event in the world, the South32 Rottnest Channel Swim is a 19.7km open-water swim from Cottesloe Beach to Rottnest Island (Wadjemup). Held in February, the event sells out annually and brings more people to Rottnest Island than any other day of the year; with over 12,000 people attending the event.

Help Australian Cancer Research Foundation (ACRF) supercharge brilliant life-saving research for all cancers and sign up to participate in this iconic event. Every dollar you raise will add up to millions of dollars of impact for the 2 in 5 Australians who will be diagnosed with cancer before the age of 85. By fundraising for ACRF, you'll be making sure the people you love don’t miss out on the cancer research they need
