If you want to check out the action on the day, there’s a few things to keep in mind.

Cottesloe Beach (Mudurup)

Come and experience the trepidation of the start! The first wave leaves at 5.45am, with the last wave leaving at 7.40am – so it’s important to make sure you get down early. Parking around the beach is limited, so make sure you plan accordingly to avoid last minute hassle.

Rottnest Island (Wadjemup)

The first swimmers will arrive at the island at around 10am, so it’s a good idea to be at the island at 9.30am. Ferries fill up quickly, so make sure you make a booking early so you don’t miss out. There’ll be sponsor activities happening all day, so you can make a day of it after the final waves of swimmers come in. The event will finish at 5pm.

Badge of honour

Show the world you’re one of a kind

Conquering the Rottnest Channel Swim is no easy feat. We don’t blame you for wanting to let everyone know about your amazing achievement – organising a solo swimmer licence plate is a great way to do this.
