The Nullarbor

The Nullarbor Plain stretches roughly 1,200 kilometres between Ceduna in South Australia and Norseman in Western Australia, making it one of the great overland drives on Earth. The name comes from the Latin "nulla arbor" — no trees — and the landscape delivers exactly that: an immense, flat expanse of limestone karst meeting the Southern Ocean at some of the most dramatic sea cliffs on the planet. For many travellers, crossing the Nullarbor is a bucket-list road trip that rivals Route 66 or Iceland's Ring Road — except here, you share the highway with wedge-tailed eagles and the occasional road train.

The Bunda Cliffs along the Great Australian Bight are the undisputed highlight. Rising up to 120 metres straight out of the ocean, these sheer limestone walls stretch for nearly 200 kilometres along the coast. Between June and October, southern right whales migrate into the Bight to calve, and the Head of Bight viewing platform gives you a bird's-eye view of mothers and calves just metres below — one of Australia's most accessible whale-watching experiences. Entry to the Head of Bight costs around $15 per adult and includes boardwalk access and interpretive signage. Binoculars are recommended but not essential — the whales are genuinely that close.

The Eyre Highway includes the longest straight stretch of road in Australia — 146.6 kilometres without a single bend between Balladonia and Caiguna. Roadhouses are spaced roughly every 150–200 kilometres, each with its own character: the Nullarbor Roadhouse, Border Village, Madura Pass, Caiguna, Balladonia, and Eucla all make worthwhile fuel-and-photo stops. Eucla's old telegraph station, half-buried by sand dunes, is one of the most photographed ruins in outback Australia. The Balladonia Roadhouse has a small museum featuring debris from NASA's Skylab space station, which famously crashed near here in 1979.

Most travellers drive the Nullarbor in a campervan or hire car over three to five days. The classic itinerary looks something like this: Day 1, Ceduna to the Nullarbor Roadhouse (around 300 km); Day 2, whale watching at Head of Bight and on to Border Village or Eucla (250–300 km); Day 3, Eucla to Balladonia via Madura Pass and the longest straight stretch (around 500 km); Day 4, Balladonia to Norseman (190 km) and then south to Esperance or north toward Kalgoorlie. Adventurous drivers can add a detour south from Norseman to Esperance and the Cape Le Grand National Park — Lucky Bay is consistently ranked among Australia's whitest beaches.

Free bush camping is permitted at designated rest areas along the highway, and the stargazing alone is worth the drive — minimal light pollution means the Milky Way stretches from horizon to horizon. Popular free camps include the Bunda Cliffs rest area (great sunset spot), the Madura Pass lookout, and several signed turn-offs between Caiguna and Balladonia. If you prefer more comfort, most roadhouses offer basic cabins or powered caravan sites for $30–$60 per night.

Nullarbor crossing costs and budget: fuel is the biggest expense — expect to pay roughly $2.20–$2.50 per litre at roadhouses, and a standard campervan uses around 12–15 litres per 100 km. Budget roughly $400–$600 in fuel for the full crossing. Groceries and supplies should be stocked up in Ceduna or Norseman, as roadhouse prices are steep. Total budget for a 4–5 day crossing in a campervan typically runs $800–$1,200 for two people including fuel, food, and the odd roadhouse meal.

Best time to cross the Nullarbor: April to October offers the most comfortable driving temperatures (15–25°C during the day) and coincides with whale season at the Bight. Summer (December–February) brings extreme heat — daytime temperatures regularly exceed 40°C across the plain, tyre blowouts become more common, and wildlife is less active. If you must drive in summer, travel early morning and late afternoon only.

Practical tips: always carry at least 10 litres of extra water per person, top up fuel at every roadhouse regardless of your tank level, check tyre pressure for the long straight stretches, and watch for wildlife — especially kangaroos and wombats at dawn and dusk. Road trains (triple-trailer trucks) share the highway and need a wide berth — pull left and slow down when one approaches. Mobile coverage is patchy to non-existent between roadhouses (Telstra has the best coverage; Optus and Vodafone have almost none), so download offline maps, carry a UHF radio or satellite communicator, and let someone know your route and expected arrival times.
