South Australian town built underground to escape extreme desert heat

At first glance, Coober Pedy looks like a sun-bleached, abandoned outpost in the middle of the unforgiving South Australian outback. Beneath its rugged, dusty surface, however, lies a sprawling, hidden network of homes, businesses and cultural landmarks carved from solid rock.

A June 18 Instagram post by EarthPix shed light on this troglodyte community, capturing the world's imagination. To escape surface temperatures that reportedly soar past 45°C (113°F), the residents of Coober Pedy didn't just build air-conditioned houses; they moved entirely underground.

Life inside a 'dugout'

The underground homes here are known to locals as 'dugouts'. Historically carved out by opal miners, these spaces utilise passive cooling, an energy-free architectural design technique that naturally protects residents from the brutal climate above.

The local weather is famously punishing. In the peak of summer, a 2023 BBC report highlighted that surface temperatures can reach a scorching 52°C (126°F). It gets so hot that electronics must be stored in refrigerators, and birds have been seen dropping out of the sky from heat exhaustion. Even the town's name reflects this harsh reality, loosely translating from an Indigenous Australian term meaning 'white man in a hole', according to the BBC.

Yet a step inside a dugout reveals a completely different world. No matter how brutal the summer heat or how bitter the winter winds, the interior temperature remains naturally stable and comfortable. Deep within the region's iron-rich sandstone, the climate is heavily moderated, similar to the ancient underground cities of Cappadocia.

An eccentric, dark and beautiful world

For the reported 60 percent of the population living below ground, evidence of their presence on the surface is subtle, limited to ventilation shafts jutting out of the earth and mounds of excess soil piled near structural entryways.

Visually, the interiors are breathtakingly raw and textured, looking straight out of a classic National Geographic feature. However, the unique lifestyle takes some getting used to. One traveller recalled their stay on a road trip, commenting on EarthPix's Instagram post: "Staying in a dugout was quite the experience! I had to sleep with the bedroom door cracked open a bit to receive ambient light from the main room... otherwise, it felt too dark and closed-in."

A look inside subterranean life

Life underground isn't just restricted to houses; the community has transitioned entirely beneath the earth's surface. Homes are cut directly into the hillsides, blending seamlessly with the terrain, while black-and-white ventilation pipes rise straight up from the rocky desert floor.

Fully functional local businesses, including bookstores and cafes, operate under roughly textured stone ceilings illuminated by fluorescent lighting. Perhaps most impressive are the town's spiritual centres. Local underground churches feature stunning stone-brick altars and religious statues tucked neatly into hand-carved rock alcoves.

How to experience it on Airbnb

Coober Pedy features a booming hospitality scene for those eager to experience this unique outback lifestyle firsthand. Vacation rentals can be affordable, with budget-friendly underground options starting at around ₹12,000 per night on Airbnb. Popular properties effortlessly blend rustic outback charm with modern comforts, think beautifully exposed, sand-coloured rock walls displaying rich natural textures, paired with cosy lighting and tiled or carpeted flooring.

But don't let the 'cave' aesthetic fool you; these properties come packed with high-speed Wi-Fi, fully equipped kitchens, laundry facilities and secure parking for outback caravans. Some even offer luxury additions like private jacuzzis and above-ground decks for stargazing. Many of these rentals are deeply tied to the town's mining history, and visitors who look closely at the bedroom walls can often spot raw, sparkling traces of precious opal still embedded directly in the rock.

Whether the idea of subterranean living seems slightly claustrophobic or brilliant, Coober Pedy stands as a testament to human ingenuity, proving that when the climate above becomes unlivable, people are capable of carving out a thriving, comfortable home down below.
