The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna.

Definitions of the Pilbara region

At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the Regional Development Commissions Act 1993; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA).

Pilbara

General

The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of . It contains some of Earth's oldest rock formations, and includes landscapes of coastal plains and mountain ranges with cliffs and gorges. The major settlements of the region are Port Hedland, Karratha and Newman. The three main ports in this region are Port Hedland, Dampier and Port Walcott.

The area is known for its petroleum, natural gas and iron ore deposits, which contribute significantly to Australia's economy. Other than mining, pastoral activities as well as fishing and tourism are the main industries.

Local government

The Pilbara region, under the Pilbara Development Commission, contains four local government areas:

Ashburton – Shire of Ashburton

East Pilbara – Shire of East Pilbara

Karratha – City of Karratha

Port Hedland – Town of Port Hedland

Etymology

The Pilbara Aboriginal Language Centre Wangka Maya says that the name for the Pilbara region derives from the Aboriginal word bilybara, meaning "dry" in the Nyamal and Banyjima languages.

Alternatively, the Western Australia Gas Industry claims that the region takes its name from pilbarra, an Aboriginal word for the mullet that is available in local waters. The Pilbara Creek (originally spelt "Pilbarra") is a tributary of the Yule River, a significant river in the region. Sea mullet and barramundi can still be caught in the Yule River today. Pilbara Goldfield, discovered in 1885, was named after the creek, and the name later became associated with the region.

History

Radiocarbon dating estimates in evidence show that rock art and standing stones at Murujuga in Dampier Archipelago, Australia's earliest known stone structures, believably dating from 6046 to 5338 BC, are of contextualization by thousands of years of unique cultural traditions and folklore. These sites have lived up as part of survival in present times.

The first European to explore the area was Francis Thomas Gregory in 1861. Within two years, European settlers had begun arriving. The region was regarded as part of the North West at first – a larger area that included the modern Kimberley and Gascoyne regions.

Settlements along the coast at Tien Tsin Harbour (later Cossack), Roebourne and Condon (officially Shellborough; later abandoned) were established over ensuing decades, mainly as centres of the rangeland livestock (grazing/pastoral) industry or pearling ports. However, as natural mother of pearl beds around Cossack were fished out, the pearling fleet began to move northward, and by 1883 it was based at Broome, in the Kimberley region. From , pastoralism went into decline with the growth of other, more productive agricultural areas of the state.

Mining in the region started on 1 October 1888, when the Pilbara Goldfield was officially declared – named after a local creek, the goldfield would later give its name to the region as a whole. It was later divided into the Nullagine Goldfield and Marble Bar Goldfield. However, gold mining began to decline in the Pilbara in the mid-1890s, after alluvial ore had been exhausted. In 1937, mining of asbestos commenced at Wittenoom Gorge. While the presence of abundant iron ore had been known for about a century, it was not until the 1960s and the discovery of high-grade ore in the Hamersley Ranges that the area became pivotal to the state's economy, and towns built to accommodate mining and allied services boomed.

In the 1950s, three British nuclear weapons tests were carried out in the Montebello Islands, 130 km (81 mi) off the Pilbara coast.
