Nullarbor Plain

The Nullarbor Plain is one of Australia’s most epic road trips—a vast, treeless limestone karst that stretches nearly 1,200 kilometres between South Australia and Western Australia. Its name, from Latin nullus arbor (no tree), hints at the stark, otherworldly beauty: endless blue skies, red dirt, and the dramatic Great Australian Bight cliffs plunging into the Southern Ocean. This is a place for travellers who crave solitude, big skies, and raw nature. The Eyre Highway, the only sealed road across the plain, offers a true outback experience with quirky roadhouses, wildlife encounters, and a sense of remoteness that’s hard to find anywhere else.

Highlights & What to See

• Bunda Cliffs – Stretching for hundreds of kilometres, these sheer white cliffs drop 60–90 metres into the Southern Ocean. Stop at the viewpoints near the Head of Bight to watch southern right whales calving (June–October).
• Head of Bight – A dedicated whale-watching platform offers some of the best land-based whale viewing in Australia. The visitor centre has excellent interpretive displays.
• Nullarbor Roadhouse – A legendary pit stop for fuel, a cold beer, and a photo with the iconic ‘Nullarbor’ sign. It’s a slice of outback hospitality.
• Cocklebiddy Cave – One of the longest cave systems in the world, accessible via a guided tour from the Cocklebiddy Roadhouse. The cave’s crystal-clear lakes are unforgettable.
• Koonalda Homestead – A historic sheep station turned roadhouse, with a fascinating museum and the chance to see ancient Aboriginal rock art in the nearby caves.
• Eucla Pass – The western gateway to the plain, where the landscape shifts to sand dunes and the abandoned Eucla Telegraph Station sits half-buried in sand.

Suggested Time to Spend

Most travellers cross the Nullarbor in 2–3 days, but to truly appreciate its scale and solitude, allow 4–5 days. Drive no more than 4–5 hours per day, stopping at roadhouses, lookouts, and short walks. The best time to visit is April to October, when temperatures are milder and whales are present. If you’re self-driving, fill up at every fuel stop—distances between services are up to 200 km.
