The Rottnest Channel Swim is one of the largest open water swims in the world and covers 19.7km from Cottesloe Beach to Rottnest Island. The swim can be undertaken solo, in teams of two or four and attracts over 10,000 spectators, supporters and competitors on the island. Last year, swimmers raised over $100,00 for Breast Cancer Care Western Australian! Curious? There’s still time to get involved!
