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 a powerful right at Caves nearby. Getting here means a very long drive west of Adelaide to Penong, then 21 km south through desert scrub. The reward is empty lineups, powerful waves, and genuine wilderness surfing. Bring everything—nearest help is hours away.

Frequently Asked Questions

What kind of wave is Cactus?

Cactus is a reef break in Nullarbor, Australia, that mostly breaks left. It's on our list of the world's 100 best waves.

What's the story behind Cactus?

Cactus is about 21 km south of Penong, with two left-handers and one right. The land around it, including Point Sinclair and the Caves break, is privately owned and run as a bush camping reserve.

What swell works best at Cactus?

Cactus picks up swell from the S round to the W, and it's best when it's coming straight out of the SW. It starts working at around 1.5m and handles up to about 3m, with the sweet spot around 2.2 to 2.6m. Period matters too: aim for 16s or longer, as anything under 12s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.

What wind is offshore at Cactus?

An ENE wind is dead offshore at Cactus, and anything from the NNE round to the ESE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

What tide is best at Cactus?

Cactus is at its best around mid tide, roughly 0.6m to 1.5m on the local chart.

When is the best time of year to surf Cactus?

The most reliable run of swell at Cactus comes Apr to Sep. There's a second window in Mar and Oct too. Winter-spring. Remote Great Australian Bight. Southern Ocean power.

How cold is the water at Cactus?

The water at Cactus averages around 17°C, so you'll want a 3/2mm fullsuit. It shifts a few degrees through the year, so check the season before you pack.

Is Cactus good for beginners?

Not really. It's rated 7/10 for difficulty and suits experienced surfers. The lineup is usually quiet (crowd 3/10). Extremely isolated. High shark activity. Help is a long way off.

How do I get to Cactus?

The nearest airport on our list is ADL, then it's roughly a 12-hour drive. Long drive west of Adelaide to Penong, then 21 km south. Bush camping on private land.

What other surf spots are near Cactus?

The closest breaks we track are Cactus Caves (1.9 km), handy when Cactus isn't working.
