Along with Broome and Kununurra, it is one of only three towns in the Kimberley to have a population over 2,000. Located on King Sound, Derby has the highest tides in Australia, with the differential between low and high tide reaching 11.8 metres (39 ft).

## History

Derby falls within Nyiginka country.
The town was founded in 1883 and named after Edward Stanley, 15th Earl of Derby, the British secretary of state for the colonies.
During World War II, Derby was bombed by Japanese planes because of an air base and jetty that was used by Australian forces. More recently, refugees were housed at Royal Australian Air Force Base Curtin, however the detention centre was closed in 2014.
Derby was famous in the 1920s as the terminus of the first scheduled aviation service in Australia, West Australian Airways Ltd. Their service began with their first flight on 5 December 1921, which crashed, near Geraldton. At one time the Perth to Derby service was the world's longest passenger airline route.
Derby Hospital treated many aboriginal patients with Hansen's Disease, then known as leprosy. The Derby Leprosarium operated from 1936 to 1986, staffed by nuns led by Sr Mary Gertrude.
In 1968 the town had a population of approximately 1,500 people, many employed at the meatworks. A A$900,000 beef road from Glenroy Station to Derby was completed the same year to assist with the development of beef processing. A A$2 million steel and concrete jetty was built in 1965 to provide adequate port facilities for the shipment of live cattle. The West Kimberley Regional Prison, whose architecture won several awards, was opened in 2012.
Local boy Jimmy Taylor disappeared from Derby on 29 August 1974 after walking to a local shop. In 2014, a coroner determined that he had died, but was unable to determine when or how, recording an open verdict. Convicted child killer James Ryan O'Neill was living in Derby at the time of Taylor's disappearance but he has denied any involvement. In 2023, a $1 million reward was offered to anyone who provided information as to what had happened to Taylor.

The Boab Festival (named after the boab tree) is a fortnight-long festival that includes traditional events such as mud football, watermelon seed spitting, the Mardi Gras and other festivities.
Historically, Derby has played a major role in the Australian Royal Flying Doctor Service for the Kimberley region.
The Kimberley School of the Air is located in Derby. The school provides education to isolated Primary-aged children living on cattle stations and in remote Aboriginal communities and outstations scattered throughout the 423,517 square kilometres (163,521 sq mi) Kimberley region.
Derby has two schools located in the town, Holy Rosary School Derby and Derby District High School. Derby District High School follows Chris Sarra's vision of "Stronger Smarter", which aims to raise the expectations of the school as a community.
Wharfinger's House Museum tells the story of the aviation history of the town as well as the history of the port. The Norval Gallery showcases the work of artist Mark Norval as well as a broad selection of Indigenous artwork from across the Kimberley.

## Economy

There is employment in the pastoral and mining industries, as well as administration and tourism. There is oil at Blina, diamond mining at Ellendale. Granite is quarried from the Wunaamin-Miliwundi Ranges and lead and zinc from Cadjebut and an iron ore mine at Koolan Island. A major mineral sands mining project is being developed at Thunderbird, 100 kilometres (62 mi) west of Derby. In 1997 the Derby wharf, which was closed in the 1980s, was re-opened for barging operations for the export of lead and zinc.
Tourism bolsters the local economy between the months of May and September.
The Derby Leprosarium on the outskirts of the town was one of two in Western Australia that helped to contain an epidemic of leprosy from the 1930s to the 1960s.
