Cactus

Nullarbor, Australia
🦈Sharks🪨Rocks🏝️Remote🚶Difficult access

Cactus is Australia's most remote quality surf zone—a collection of breaks at the edge of the Nullarbor Plain in South Australia, where the Southern Ocean delivers raw power to an isolated stretch of coastline. The main break is a hollow left that peels along a limestone reef, with nearby spots including the slab Supertubes. Getting here requires a 12-hour drive from Adelaide through desert scrub. The reward is empty lineups, powerful waves, and genuine wilderness surfing. Bring everything—nearest help is hours away.
