South Head Roughwater (NSW)

The South Head Roughwater is one of Sydney’s premier marathon ocean swims, featuring a ~10km point-to-point course from Bondi Beach to Watsons Bay. The route follows the exposed coastline around South Head before entering Sydney Harbour for a unique harbour finish, combining open ocean swimming with an iconic urban backdrop.

Recognised as the pinnacle endurance swim on the Sydney ocean calendar, the event is a true test of navigation, ocean awareness and resilience. Swimmers are exposed to swell, currents and changing conditions along a largely unprotected coastline, making it a significant step up from typical ocean swims and a key benchmark for those progressing toward longer marathon distances.

Qualification Requirements:

• Demonstrated ocean swimming capability (typically 5km+ open water experience)

• Competency and safety requirements apply

Approx. Date: Mid–late May (typically third Sunday in May)

Registrations Open: Early March – mid May (online entry)
