The Kimberley is the northernmost of the nine regions of Western Australia. It is 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 in the region of the Pilbara, and on the east by the Northern Territory.
The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley.

Deserts cover about 1,371,000 km (529,000 sq mi), or 18%, of the Australian mainland, but about 35% of the Australian continent receives so little rain, it is practically desert. Collectively known as the Great Australian desert, they are primarily distributed throughout the Western Plateau and interior lowlands of the country, covering areas from South West Queensland, the Far West region of New South Wales, Sunraysia in Victoria and Spencer Gulf in South Australia to the Barkly Tableland in Northern Territory and the Kimberley region in Western Australia.
By international standards, the Great Australian desert receives relatively high rates of rainfall, around 250 mm (10 in) on average, but due to the high evapotranspiration it would be correspondingly arid. No Australian weather stations situated in an arid region record less than 100 mm (3.94 in) of average annual rainfall. The deserts in the interior and south lack any significant summer rains. The desert in western Australia is well explained by the little evaporation of the cold sea current of the West Australian Current, of polar origin, which prevents significant rainfall in the interior of the continent. About 40% of Australia is covered by dunes. Australia is the driest inhabited continent, with the least fertile soils.
The Bungle Bungle Range is a major landform and the main feature of the Purnululu National Park, situated in the Kimberley region of Western Australia.
Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a land area of 2,527,013 square kilometres (975,685 sq mi), and is also the second-largest subdivision of any country on Earth.
Western Australia has a diverse range of climates, including tropical conditions in the Kimberley, deserts in the interior (including the Great Sandy Desert, Little Sandy Desert, Gibson Desert, and Great Victoria Desert) and a Mediterranean climate on the south-west and southern coastal areas. As of June 2024, the state has 2.965 million inhabitants—10.9 percent of the national total. Over 90 percent of the state's population live in the south-west corner and around 80 percent live in the state capital Perth, leaving the remainder of the state sparsely populated. The Trans-Australian Railway and the Eyre Highway traverse the Nullarbor Plain in the state's south-east, providing the principal connection between Western Australia and the population centres in the eastern states.
Thermal lows, or heat lows, are non-frontal low-pressure areas that occur over the continents in the subtropics during the warm season, as the result of intense heating when compared to their surrounding environments. Thermal lows occur near the Sonoran Desert, on the Mexican Plateau, in California's Great Central Valley, in the Sahara, in the Kalahari, over north-west Argentina, in South America, over the Kimberley region of north-west Australia, over the Iberian Peninsula, and over the Tibetan Plateau.
On land, intense, rapid solar heating of the Earth's surface causes the heating of the lowest layers of the atmosphere, via re-radiated energy in the infrared spectrum. The hotter air is less dense than surrounding cooler air and rises, leading to the formation of a low-pressure area. Elevated areas can enhance the strength of the thermal low because they warm more quickly than the atmosphere which surrounds them at the same altitude. Over water, instability lows form during the winter when the air overlying the land is colder than the warmer water body.
The Purnululu National Park is a World Heritage Site in the East Kimberley region of Western Australia. The 239,723-hectare (592,370-acre) national park is located approximately 300 kilometres (190 mi) south of Kununurra, with Halls Creek located to the south. Declared a World Heritage Site in 2003, the park was inscribed as follows:
The Great Sandy Desert is an interim Australian bioregion, located in the northeast of Western Australia straddling the Pilbara and southern Kimberley regions and extending east into the Northern Territory. It is the second largest desert in Australia after the Great Victoria Desert and encompasses an area of 284,993 km (110,036 sq mi). The Gibson Desert lies to the south and the Tanami Desert lies to the east of the Great Sandy Desert.
Noonkanbah Station (or just Noonkanbah) is a pastoral lease, both a cattle and sheep station, on the Fitzroy River between Camballin and Fitzroy Crossing in the south central Kimberley region of Western Australia.
The station was pegged out in the 1880s and covered approximately 4,000 square kilometres (1,500 sq mi). It was the subject of an infamous land-rights dispute in August 1980 when state premier Sir Charles Court enforced an oil exploration project under police protection. The traditional owners now control around 1800 square kilometres of the land sacred to the Yungngora Community.
The Dampier Peninsula monitor or Dampier Peninsula goanna (Varanus sparnus), described in 2014, is the smallest known species of monitor lizard, growing up to 16.3 grams with a length of almost 23 cm and a SVL (snout to vent length) of 116 mm. It is believed to live only on the Dampier Peninsula of the Kimberley region north of Broome and Derby in Western Australia. It is highly active, making it difficult to photograph in the wild. It has short legs, an elongate body, a reddish-brown back with widely scattered black spots and "a ridged, circular and short prehensile tail."
Broome, also known as Rubibi by the Yawuru people, is a coastal pearling and tourist town in the Kimberley region of Western Australia, 2,046 km (1,271 mi) north of Perth. The town recorded a population of 14,660 in the 2021 census. It is the largest town in the Kimberley region.
