An offshore marine sanctuary off northwest Western Australia, known for sea turtles, coral reefs, and a layered history of nuclear testing and gas extraction.
Montebello Islands Marine Park
The Montebello Islands Marine Park is an offshore protected area lying off the northwest coast of Western Australia, roughly 1,600 kilometres north of Perth and about 120 kilometres west of Dampier. It encompasses the entire Montebello Islands group, a scattered archipelago set in the warm tropical waters of the Indian Ocean where the continental shelf gives way to deeper oceanic environments.
The park is recognized as one of the most important marine turtle breeding and nesting areas along the Western Australian coast, and it protects a richly diverse reef system with extensive coral, fish, echinoderm, and mollusc communities. The marine park sits within a wider regional landscape that also includes the Barrow Island Marine Park and the Barrow Island Marine Management Area, creating a large contiguous zone of protected marine habitat.
The region's identity is shaped by its unusual combination of ecological richness and industrial significance. The waters around the Montebello Islands neighbour the Gorgon gas field, one of Australia's most important hydrocarbon extraction zones, while the islands themselves carry an enduring legacy from British-Australian atomic weapons tests carried out in the early 1950s. Together these layers of natural, industrial, and historical significance give the marine park a distinctive profile within Australia's network of marine protected areas.
