The Kimberley is one of the nine regions of Western Australia. It is located in the northern part of Western Australia, bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy and Tanami Deserts, and on the east by the Northern Territory.

The region was named after the Kimberley diamond fields in South Africa. This was due to the two areas sharing a similar landscape.[1] The discovery of diamonds in the Kimberley region has subsequently added to the likeness.

History

The Kimberley was one of the earliest settled parts of Australia, with the first arrivals landing about 40,000 years ago from the islands of what is now Indonesia.

In 1837, with support from the Royal Geographical Society, Lieutenants George Grey and Franklin Lushington, and 12 men sailed on the schooner Lynher from Cape Town reaching Hanover Bay on 2 December 1837. The party started inland on 19 January 1838[2]. Leaders and men were totally inexperienced, progress was delayed by flooded country, many stores were abandoned, and the party was constantly split up despite the presence of large numbers of hostile Aboriginals. On 11 February Grey was speared and became critically ill, but after two weeks continued the exploration. The party discovered and named the Glenelg River, Stephen Range and Mount Lyell before returning to Hanover Bay in April. There they were picked up by the Beagle and Lynher and taken to Mauritius to recuperate.[3]

In 1879 Alexander Forrest trekked across from the western coast to the [[Northern Territory]. Forrest named the Kimberley district, and discovered the Margaret and Ord Rivers, the King Leopold Ranges, and the fertile area between the Fitzroy and Ord River.[4] He subsequently set himself up as a land agent specialising in the Kimberley and was thus instrumental in the leasing of over 51,000,000 acres (210,000 km2) in the region during 1883.

In 1881, Philip Saunders and Adam Johns, in the face of great difficulties and dangers found gold in various parts of the Kimberley. Early in 1881 the first five graziers, who called themselves the Murray Squatting Company, took up 120,000 behind Beagle Bay and named it Yeeda Station.[4] They became the first men to shear sheep in the southern Kimberley in 1883. There was further European settlement in 1885, when cattle were driven across Australia from the eastern states in search of good pasture lands. Many other Europeans arrived soon after, when gold was discovered around Halls Creek.

In the 1890's the area was the site of an armed insurrection of indigenous people under the leadership of Jandamarra, a Bunuba warrior[5].

The only Japanese force which landed in Australia during World War 2 was a small reconnaissance party which landed in the Kimberley on 19 January 1944 to investigate reports that the Allies were building large bases in the region. This party consisted of four Japanese officers on board a small fishing boat and it investigated the York Sound region for a day and a night before returning to Kupang in Timor on 20 January. When he returned to Japan in February, the junior officer who commanded the party suggested using 200 Japanese prison inmates to launch a guerrilla campaign in Australia. But nothing came of this and the officer was posted to other duties.[6]

The population of the Kimberley is only about 41,000, but this figure is growing at a rate of 4.8% per year, around three times the state average. The population is fairly evenly distributed, with only three towns having populations in excess of 2,000: Broome (15,000), Derby (3,600) and Kununurra (5,000). Approximately 33% of the region's population are of Aboriginal descent.

Politics

At federal level, the Kimberley is represented by the member for Durack. At state level, the Kimberley electorate takes in most of the region and all of its major towns, while Pilbara includes south-eastern areas such as Halls Creek and Fitzroy Crossing.

The Kimberley region consists of the local government areas of Broome, Derby-West Kimberley, Halls Creek and Wyndham-East Kimberley.

Geography

Lennard River in the Kimberley region of Western Australia

The Kimberley is an area of 423,517 square kilometres (163,521 sq mi), which is about three times the size of England or twice the size of Victoria.

The Kimberley consists of the ancient, steep-sided mountain ranges of northwestern Australia cut through with sandstone and limestone gorges and steep ridges from which the extreme monsoonal climate has removed much of the soil. The southern end of the Kimberley beyond the Dampier Peninsula is flatter with dry tropical grassland and is used for cattle ranching. In parts of the Kimberley such as the valleys of the Ord and Fitzroy Rivers in the south the soils are relatively usable cracking clays, whilst elsewhere they are lateritic Orthents. Although none of the mountains reach even 1,000 metres (3,281 ft), there is so much steep land as to make much of the region very difficult to traverse, especially during the wet season when even sealed roads are often flooded. The coast is typically steep cliffs in the north but flatter in the south, all subject to high tides.

The Kimberley has a tropical monsoon climate. The region receives about 90% of its rainfall during the short wet season, from November to April, when cyclones are common (especially around Broome) and the rivers flood. The annual rainfall is highest in the northwest, where Kalumburu and the Mitchell Plateau average 1,270 millimetres (50 in) per year, and lowest in the southeast where it is around 520 millimetres (20 in). In the dry season, from May to October, south easterly breezes bring sunny days and cool nights. Climate change since 1967 has led to large increases of as much as 250 millimetres (10 in) per year in annual rainfall over the whole region. Recent studies suggest Asian pollution and not global warming as the cause of this increased rainfall.[7] In 1997 and 2000 the region received especially heavy rains, leading to record flooding of the Fitzroy and other rivers.

The Kimberley is one of the hottest parts of Australia, with the average annual mean temperature around 27 °C (81 °F), and with mean maximum temperatures almost always above 30 °C (86 °F) even in July and ranging in November before the rains break from 37 °C (99 °F) on the coast to 40 °C (104 °F) in the south around Halls Creek. Mean minima in July range from around 12 °C (54 °F) in the south to 16 °C (61 °F) around Kalumburu, whilst in November and December they are generally around 26 °C (79 °F).[8]

The aboriginal people of the Kimberley recognise 6 traditional seasons based on meteorological events as well as observed events relating to fauna and flora.

Geology

During the Devonian period, a barrier reef system formed before a subsequent drop in sea levels over the Kimberley. This reef system was similar to the Great Barrier Reef and is still visible today in the form of the Napier Range and the Ningbing Range. Some of the features are Tunnel Creek, Windjana Gorge and Geikie Gorge.[9]

This area is also known as the Kimberly Block physiographic province, of which it is part of the larger West Australian Shield division. This province contains the King Leopold Range, Durack Range, Leveque Rise, Browse Depression, and Londonderry Rise physiographic sections.The Aboriginals used this to their advantage.

Ecology

The rugged and varied sandstone landscape is home to a distinctive mixture of wildlife which has been thoroughly mapped and described by the Western Australian Department of Conservation and Land Management.[10][11][12][13][14][15][16][17][18][19][20] There are similar habitats to the Kimberley across the border in the Northern Territory including the valleys of the Victoria and Daly Rivers but these have been less carefully studied.[21][22]

Flora

Much of the Kimberley is chiefly covered in open savanna woodland dominated by low bloodwood and boab trees (Adansonia gregorii) with Darwin stringybark and Darwin woollybutt eucalypts in the wetter areas. The red sandy soil of the Dampier Peninsula in the south is known for its characteristic pindan wooded grassland while in the more fertile areas like the Ord valley the trees are grasslands of Chrysopogon, Aristida, Dicanthium and Xerochloa (rice grass) in the wetter valleys. The banks of the Ord, Fitzroy and other rivers are home to a greater variety of vegetation while in sheltered gorges of the high rainfall north there are patches of tropical dry broadleaf forest, called monsoon forests, deciduous vine forest or vine thicket in Australia (often mistakenly called 'dry rainforest'), which were unknown to science until 1965[23] and are one of the most floristically rich parts of Australia outside the Wet Tropics and southwestern WA. There are also areas of mangrove in river estuaries where the coast is flatter.

Fauna

Animals found here include the huge saltwater crocodile and a rich variety of birds such as the Channel-billed Cuckoo, Pacific Koel, and Purple-crowned Fairywren. The sandstone gorges of north Kimberley are an important refuge for a particularly rich collection of endemic species including some that have disappeared from the flatter areas including for example the purple-crowned fairywren, the endangered Gouldian Finch and a large number of frogs: Flat-headed Frog, Cave-dwelling Frog, Magnificent Tree Frog, Derby Toadlet, Small Toadlet, Fat Toadlet, the unconfirmed Marbled Toadlet, Mjoberg's Toadlet, Mole Toadlet and Stonemason's Toadlet. Mammals that have declined especially in the flatlands include the bilby, Northern Quoll, Pale Field Rat, Golden-Backed Tree Rat, and Golden Bandicoot.

The gorges of central Kimberley known for their fossils and for their large colonies of bats include Windjana, Tunnel Creek, and Geikie Gorges. Lake Argyle and other wetlands of the Ord and the Kimberley are important habitats while there are important populations of shorebirds in the Ord estuary, Eighty-mile Beach and Roebuck Bay, which has been described as "one of the most important stop-over areas for shorebirds in Australia and globally".[24] Finally there are a number of rocky islands off the north coast that are home to birds and turtles.

Threats and preservation

Little of the Kimberley has been subject to wholesale clearance other than particularly fertile parts of the Ord Valley (and areas of Kimberley-type habitat across in the Daly River basin in the Northern Territory) but the pastureland in the southern areas has been affected by 100 years of livestock grazing and other threats including introduced weeds (such as cocklebur, parkinsonia, bellyache bush and castor oil plant), feral cats and changes to traditional Aboriginal fire regimes (the way grassland is burnt and allowed to renew). However the remote sandstone areas to the north have valuable original habitat in good condition providing shelter for much wildlife.

The largest protected areas are the Prince Regent Nature Reserve and the Drysdale River National Park along with Gregory National Park and Keep River National Park across in the Northern Territory which preserve similar habitats, (and indeed Keep River's nearest town is Kununurra in the Kimberley).

Purnululu National Park contains the sandstone domes of the Bungle Bungle Range.

The Kimberley is a popular tourist destination, with areas such as the Bungle Bungle, the Gibb River Road, Lake Argyle, El Questro Station, Horizontal Falls and Cape Leveque. The Gibb River Road and the road into the Bungle Bungles can at times be accessed in a two-wheel drive car, although one can access many additional areas in a four-wheel drive vehicle.

Other parks in the region include Geikie Gorge National Park, Mirima National Park, Mitchell River National Park, Point Coulomb National Park, Purnululu National Park, Tunnel Creek National Park, Windjana Gorge National Park and Wolfe Creek Meteorite Crater National Park

Economy

The town of Broome has a flourishing pearling industry which operates around the Kimberley coast. Some of the major farmers are Paspaley Pearls, Clipper Pearls, Broome Pearls and the Willie Creek Pearl Farm.

One third of the world's annual production of diamonds is mined at the Argyle and the Ellendale diamond mines. Oil is extracted from the Blina oil field and gas is expected to be taken from offshore sources soon. Zinc and lead were mined at the Pillara and Cadjebut mines near Fitzroy Crossing with Nickel still being mined at Sallay Mallay near Halls Creek. Derby is the nearest export base for shipping these metals.

Traditionally, the economy depended on pastoral leases - with most of the region covered by the leases.

More recently agriculture has been focused on the Ord River Irrigation Area near Kununurra. Irrigation was also trialled in the West Kimberley by way of the now defunct Camballin Irrigation Scheme. There are also fruit growers in Broome and in other areas in the West Kimberley. Beef cattle are grown in the Kimberley and exported live. Wyndham features the last remaining meatworks in the Kimberley - there were formerly works at Broome and Derby but financial constraints have caused these to be closed.

Barramundi are bred in Lake Argyle; and Broome features a fully equipped Aquaculture Park near the port which is tenanted by amongst others Paspaley Pearls and Broome TAFE. The Kimberley also has a thriving fishing industry.

Some of Australia's most prominent indigenous artists and art centres are in or adjacent to the Kimberley region. Artists such as Paddy Bedford and Freddy Timms have an international profile, and there are a number of Aboriginal-owned and controlled art centres and companies that assist artists, arrange exhibitions and sell works. The art centres in the region are also organised through the Association of Northern, Kimberley and Arnhem Aboriginal Artists. Issues have been raised regarding the exploitation of indigenous artists by businesses and individuals, including in the Kimberley, which were canvassed in an Australian Senate parliamentary committee report.
