The South Head Roughwater is the crown jewel of Sydney’s ocean swim season. At 10km, it’s the most challenging and prestigious swim on the circuit, tracing the coastline from the famous Bondi Beach, around the cliffs of South Head, and into Watsons Bay.

For experienced ocean swimmers, this is your marathon. A test of endurance, navigation, and mental grit, rewarded by panoramic views, strong currents, and an iconic finish inside the harbour. The swim runs with the swell, making it as scenic as it is strategic.

This is the swim you train for. This is the swim you remember.

Note: Please read the Know Before You Go section for important details about the four-step entry process.

What's on offer

10km Ocean Swim

South Head Roughwater

15 years

This is the kind of swim that ocean dreams are made of. Starting on the sand at North Bondi, you’ll head straight out to Ben Buckler – via the shark buoy – round the iconic headland, and follow the cliffs north along Sydney’s rugged and jaw-droppingly beautiful coastline. After soaking up the open ocean, you’ll enter the calm embrace of Sydney Harbour, gliding past Camp Cove, then veering left into Watsons Bay, where the finish line awaits in front of the Vaucluse Yacht Club (just 200m south of the Watsons Bay Hotel). It’s a true journey swim, 10km of caves, cliffs, currents and crystal-blue views. Most swimmers finish between 2–4 hours, and while it’s solo in the water, having an escort paddler is optional but highly recommended (think of them as your oceanside kick). If you’re looking to level up and tick off one of Sydney’s most spectacular long-distance swims, this is your stretch of sea.

What to expect in the water

Expect rolling swell, deep water, and changing conditions as you round the Head. Water temperatures in May typically hover around 20°C but can vary. Conditions are heavily weather-dependent and reviewed right up to event day.

Swimmer essentials

Wetsuits permitted. This is a swim for advanced ocean swimmers with marathon fitness and navigation skills. Escort paddlers are strongly encouraged, and are required for certain categories. Detailed safety and support boat/crew guidelines will be provided upon registration.

Swim aids & wetsuits

Wetsuits and flippers may be worn; however, you will not be in the running for a top-three place.

Wetsuits not eligible for prizes
Wetsuits are fine to wear, keep in mind they’re not eligible for prizes or age group placings on the day.

Swim aids allowed, not eligible for prizes
Swim aids such as fins and snorkels are welcome. You’ll still be timed, but not eligible for prizes or age group placings.

Getting there & around

Swimmers will check in at North Bondi before making their way to the start line on the beach. Transport to the start is not provided, so you’ll need to plan ahead. Most swimmers arrange a support crew or buddy to handle gear and post-swim logistics, especially helpful if you’re finishing at Watsons Bay and want dry clothes, snacks, or a big cheer waiting at the end.

Watsons Bay is easily accessible via ferry back to the city, with services running regularly to Circular Quay (a perfect scenic cool-down). For those heading back to Bondi, shuttle transport may be available – keep an eye out for updates from organisers closer to the day.
Public transport options:

To Bondi: Catch the 333, 380 or 381 buses from Bondi Junction train station, they all stop close to the beach.

From Watsons Bay: Hop on a Sydney Ferry to Circular Quay or a Captain Cook Cruise, both offering regular services. Buses like the 324 or 325 also connect Watson’s Bay to the eastern suburbs and the city.

Parking at Bondi and Watsons Bay can be tricky; arrive early, consider carpooling, or rely on public transport to keep things smooth and stress-free.

While you're there

Celebrate your swim (and your sore shoulders) in true Sydney style. Watsons Bay is made for post-swim hangs, think cold drink in hand, salty hair, and a view across one of the world’s most iconic harbours. Head straight to the Watsons Bay Hotel for a classic pub feed with a view, or spread out a towel under the Moreton Bay figs in Robertson Park for a relaxed picnic.

Feeling fancy? Treat yourself to fresh seafood from Doyles on the Wharf. Or just grab a cone and wander the jetty, you’ve earned it.

For the still-energised, take a walk up to The Gap lookout for dramatic cliffside views (yes, that’s the coastline you just swam along). Or cool off with a quick dip at Camp Cove before jumping on the ferry home.

You’ll never look at the harbour or coastline the same way again, and neither will your mates when you tell them you swam it.
