Deep in the harsh deserts of South Australia, where summer temperatures soar to 50°C (122°F), lies a town unlike any other: Coober Pedy. From the surface, it looks like a small outback settlement, but beneath the red, sun-scorched soil lies a hidden underground city—a world carved out of rock, where life thrives despite one of the harshest climates on Earth.
The Opal Capital of the World
Coober Pedy’s story began in 1915, when a young prospector discovered opal, a gemstone famous for its fiery colors. This discovery sparked a mining boom, and today, the town still produces over 70% of the world’s opals. Mining isn’t just an industry here—it’s a lifestyle that has shaped the community’s very way of living.
Life Underground: A Unique Solution to Extreme Heat
With surface temperatures often unbearable, locals turned to the earth for shelter. Residents carved homes directly into the rocky hillsides, creating “dugouts”—naturally insulated dwellings that remain a cool 22°C (72°F) year-round.
But these aren’t just homes. Coober Pedy’s underground world includes:
- Churches and chapels carved into rock
- Hotels where visitors can sleep in cool cave rooms
- Bars, shops, and galleries built entirely below ground
- Museums and tunnels that showcase the town’s mining heritage
Walking through these subterranean spaces feels like stepping into a different world, where architecture and necessity merge seamlessly.
A Lunar Landscape Above
Step outside, and Coober Pedy’s surroundings resemble the surface of Mars. Thousands of mine shafts, piles of excavated rock, and craters dot the landscape. This surreal scenery has made the town a popular filming location for science fiction movies like Mad Max: Beyond Thunderdome and The Chronicles of Riddick.
Mining: The Heartbeat of the Town
Mining remains central to Coober Pedy’s identity. Generations of families have dug through the earth in search of opals, each stone representing hope, perseverance, and sometimes heartbreak. Visitors can even try their luck by “noodling”—sifting through discarded rock piles in search of overlooked gems.
Thriving Against the Odds
Despite its remote location and unforgiving climate, Coober Pedy is vibrant and welcoming. It boasts festivals, cultural exhibits, and art galleries showcasing Indigenous and local artists. Residents joke that they “live like moles,” but their creativity and resilience have transformed this desert outpost into a thriving hub of history and culture.
Why Coober Pedy Is a Must-Visit Destination
For travelers, Coober Pedy offers a once-in-a-lifetime experience:
- Sleep in a cave hotel

This underground city is a powerful reminder of humanity’s ability to adapt. What began as a mining settlement is now a living testament to resilience, where the magic of opals and the stark beauty of the Australian outback collide.
