Burrup Peninsula

The Burrup Peninsula is a significant geographic and cultural location in the Pilbara region of Western Australia.

Formerly known as Dampier Island, it was once a separate island within the Dampier Archipelago. In 1963, it became a peninsula when a causeway connected it to the mainland for roads and railways. Today, the area is often referred to as Murujuga. This region encompasses the town of Dampier and the Murujuga National Park. It is also home to the Murujuga Cultural Landscape, which was designated as a World Heritage Site in July 2025.

The peninsula is scientifically notable for its ancient geological foundation. Most of the rock art in Murujuga is located on igneous rocks that are 2.7 billion years old. Igneous rock forms from the cooling of molten material. These specific rocks consist of granophyre, gabbo, dolerite, and granite. The rock art itself, known as petroglyphs, was created through a specific etching process. Artists removed the outer millimeters of red-brown iron oxide. This process exposed a pale, centimeter-thick layer of weathered clay underneath. This created a visual contrast that allowed the carvings to remain visible.

Murujuga contains the world's largest and most significant collection of petroglyphs. There are approximately one million engravings across the peninsula and its surrounding islands. Some of these carvings are estimated to be between 40,000 and 50,000 years old, with some dating back over 45,000 years. Many of these images depict the thylacine, also known as the Tasmanian tiger, which is now an extinct animal. Beyond the art, the area includes roughly 2,500 archaeological sites. These sites consist of quarries, campsites, and shell middens, which are mounds of shells left by ancient people.

The traditional owners of Murujuga are the Yaburara (Jaburara) people. In Ngayarda languages, the name Murujuga is thought to mean "hip bone sticking out." This name likely refers to how certain rock blocks appear in the landscape. Following the Flying Foam Massacre between February and May 1869, five clans became the traditional custodians of the land. These groups include the Yaburara, Ngarluma, Mardudhunera, Yindjibarndi, and Wong-Goo-Tt-Oo peoples. For these groups, the rock art is not just history; it archives their lore, Dreaming stories, and Songlines.

Industrial development has created a long-standing conflict regarding the use of this land. In 1996, a land use plan divided the peninsula into two distinct zones. One area, covering 62% of the Burrup, was set aside for conservation, heritage, and recreation. The remaining 38% was designated as an industrial area for port sites and strategic industry.

Between 1963 and 2006, approximately 900 sites were destroyed to make way for these industrial projects. This represents about 24.4% of the rock art on the peninsula. However, the Western Australian government has suggested a lower figure of 4% of sites destroyed.

Scientific debate continues regarding the impact of atmospheric pollution on the petroglyphs. Some independent academics and researchers argue that industrial emissions cause physical damage. They suggest that acidic dust pollution combines with water to form acids. These acids can dissolve manganese and iron compounds in the rock. This process causes the fragmentation of the rock varnish and patina, which is the protective surface layer. While the government and industry state there is no ongoing damage from pollution, the area remained on the World Monuments Fund's list of 100 Most Endangered Places as recently as 2011.

The tension between economic prosperity and heritage preservation remains a central theme. The region is a major hub for the gas and oil industry, including projects like the North West Shelf Gas Plant and the Scarborough project. While the site was added to the Australian National Heritage List in 2007, managing the coexistence of industry and archaeology is difficult. The Murujuga Aboriginal Corporation represents Traditional Owners for certain industrial agreements. As new projects like the Scarborough project move toward production in 2026, research continues into how increased emissions might affect the ancient rock art.
