Embarking on a road trip from Port Augusta to Alice Springs is an adventure that takes you through the very core of Australia. This inland route via Roxby Downs and The Henbury Meteorite Craters offers a unique glimpse into the country’s vast and varied landscape, from coastal regions to the red centre. Let’s explore this remarkable journey and its highlights.

The Route:

Port Augusta – Pimba – Roxby Downs – Lake Hart – Coober Pedy – Marla – NT/SA Border – Henbury Meteorite Craters – Alice Springs

The journey from Port Augusta to Alice Springs spans approximately 1,400 kilometres, traversing some of the most remote and captivating terrain in South Australia and the Northern Territory. The inland route takes you north from Port Augusta along the Stuart Highway, deviating slightly to visit Roxby Downs before returning to the highway and continuing north through Coober Pedy, across the Northern Territory border, past the Henbury Meteorite Craters, and finally into Alice Springs.

Take a break: This is a huge drive and night travelling is strongly discouraged due to the risk posed by stock on the roads. At a minimum, take an overnight stop at Coober Pedy or Marla and make it a two day drive. Better still add another stop along the way and take three days and really dig deep in your discovery itinerary. If you are not ‘free camping’, remember to book your accomodation before leaving home to make sure you have a bed for the night.

  • Port Augusta: Gateway to the Outback
    Your journey begins in Port Augusta, a city situated at the head of the Spencer Gulf. Known as the “Crossroads of Australia,” Port Augusta serves as a vital link between the country’s south, north, east, and west. Before hitting the road, take time to visit the Australian Arid Lands Botanic Garden, showcasing the diverse flora of the region and offering stunning views of the Flinders Ranges.
  • Roxby Downs: A Modern Oasis
    About 250 kilometres north of Port Augusta lies Roxby Downs, a purpose-built mining town that appears like a mirage in the desert. This modern settlement, established to service the Olympic Dam mine, provides a fascinating contrast to the surrounding arid landscape. While in Roxby Downs, you can learn about the area’s rich mineral deposits and the town’s unique history at the Roxby Community Library and Cultural Centre.
  • Coober Pedy: The Underground City
    Continuing north for another 400 kilometres brings you to the iconic opal mining town of Coober Pedy. Known as the “opal capital of the world,” this remarkable settlement is famous for its underground dwellings, called “dugouts,” which protect residents from the scorching desert heat. Visit the underground churches, museums, and even hotels to experience this subterranean lifestyle firsthand. Don’t miss the chance to fossick for opals or explore the otherworldly landscapes of the nearby Breakaways Conservation Park.
  • The Northern Territory / South Australia border
    As you cross the border into the Northern Territory, the landscape transforms. The flat, arid plains give way to more varied terrain, with rocky outcrops and sparse vegetation dotting the horizon. This stretch of the journey offers a true sense of the vastness of the Australian outback, with long stretches of open road punctuated by the occasional roadhouse offering fuel, refreshments, and a chance to stretch your legs.
  • The Henbury Meteorite Craters: A Cosmic Collision
    About 145 kilometres south of Alice Springs, a short detour off the Stuart Highway leads to one of the route’s most intriguing attractions: the Henbury Meteorite Craters. This cluster of 12 craters was formed approximately 4,700 years ago when a meteorite, weighing several tonnes, broke apart and slammed into the Earth’s surface. The largest crater measures about 180 metres in diameter and 15 metres deep. Walking the self-guided trail around the craters offers a unique opportunity to contemplate the cosmic forces that have shaped our planet.
  • Alice Springs: The Heart of Australia
    Your journey culminates in Alice Springs, the iconic outback town that serves as the gateway to central Australia’s natural wonders. Nestled between the MacDonnell Ranges, “The Alice” offers a blend of Aboriginal culture, pioneer history, and modern amenities. Visit the Alice Springs Desert Park to learn about the region’s unique ecosystems, explore the historic Telegraph Station, or take in panoramic views of the town and surrounding landscape from Anzac Hill.
