Crocodile Harry's Underground Nest

Crocodile Harry's Underground Nest is an eccentric underground dugout home and museum on Crowders Gully Road in Coober Pedy, South Australia. Created and inhabited by Latvian-born Arvid Blumenthal, known as Crocodile Harry, from the 1970s until 2006, the labyrinthine residence is carved into the hillside and filled with eclectic sculptures, paintings and memorabilia. Notable as a filming location for Mad Max Beyond Thunderdome, it exemplifies Coober Pedy's distinctive underground living tradition.

Visitors can explore a maze-like underground dugout carved into sandstone, with low ceilings, narrow tunnels and multiple small rooms. The interior is densely decorated with handmade sculptures, wall carvings, paintings, bottles, and memorabilia left by Crocodile Harry and visitors. The site includes his former living quarters, kitchen and bedroom areas, an underground bar area, and outdoor skeletal and art installations. It is a self-guided, walk-through experience showcasing outsider art and the opal-mining dugout lifestyle.
