Pilbara
The Pilbara is a expansive semi-arid region in north-western Western Australia, encompassing 507,896 square kilometres and featuring ancient geological formations over 3.6 billion years old, rugged terrain including the Hamersley Range, and a coastline along the Indian Ocean.[1][2] The area supports a sparse population of approximately 60,000 residents, concentrated in coastal centres such as Port Hedland and Karratha, with the interior dominated by mining operations and pastoral stations.[3][4] The region's economy is overwhelmingly driven by resource extraction, particularly iron ore, which originates from massive deposits in the Pilbara and accounts for the majority of Australia's exports of the mineral, fuelling global steel production since large-scale development began in the 1960s.[5][6] Additional industries include liquefied natural gas processing and salt production, contributing to the Pilbara's outsized role in Western Australia's gross domestic product despite its remoteness and challenging climate marked by extreme heat and occasional cyclones.[7][8] Pilbara holds profound cultural importance for Indigenous Australian peoples, who have inhabited the area for at least 30,000 years, maintaining traditions tied to the land and preserving one of the world's largest assemblages of ancient rock art, particularly on the Burrup Peninsula.[9][7] European exploration and settlement from the 19th century introduced pastoralism and mining, transforming the landscape through infrastructure like railways and ports, though these activities have intersected with Indigenous land rights and heritage preservation efforts.[10][6]
