RAAF Base Curtin is a joint military and civil airfield on the remote north coast of Western Australia, roughly 35 kilometres southeast of Derby and 170 kilometres east of Broome. One of only three Royal Australian Air Force 'bare bases', it offers a single very long, lit hard-surface runway that makes it a distinctive and useful stop for pilots operating in the Kimberley region.
RAAF Base Curtin is a joint use Royal Australian Air Force military air base and civil airport on the north coast of Western Australia, operated by the Department of Defence and, for civil purposes, under a lease arrangement with the Shire of Derby-West Kimberley. It is one of the RAAF's three 'bare bases', meaning it holds no permanently based flying units in peacetime and is instead kept ready by a small caretaker garrison for rapid activation during exercises or operations. For a simulator pilot, Curtin is notable for its single, exceptionally long runway set in an isolated stretch of the Kimberley coast, and for its history as a purpose-built Cold War-era strategic airfield.
The base lies about 19 nautical miles (35 kilometres) southeast of the town of Derby, Western Australia, and roughly 170 kilometres east of Broome, on the northern coast of the state. It sits within a large 25,000-hectare site and is a joint use aerodrome, combining RAAF military operations with civil access under a lease agreement with the Shire of Derby-West Kimberley. Brisbane Centre provides area coverage in the vicinity, with a dedicated ground frequency listed for the base.
Curtin has a single physical runway, 11/29, oriented roughly northwest-southeast. It is 9,977 feet long, has a hard (asphalt) surface, and is lit, reflecting its origin as a purpose-built strategic military strip capable of handling large aircraft. There is no ILS approach available.
Published frequencies for Curtin include an approach frequency of 26.14 MHz, an ATIS on 31.63 MHz, a common traffic advisory frequency (CTAF) of 126.7 MHz, and a flight service frequency of 122.1 MHz. Ground movements are handled on 26.46 MHz under Brisbane Centre, with a tower frequency of 118.3 MHz also listed for the field.
No specific published circuit heights, joining instructions, or noise abatement procedures for Curtin are available in the sources reviewed; pilots should expect to use the CTAF of 126.7 MHz for traffic calls and coordinate with the tower frequency of 118.3 MHz when the base is active, bearing in mind its role as a military bare base that may see periodic activation for exercises.
RAAF Curtin was the first major new military airfield built in Australia since the Second World War, with construction beginning in 1983. It was officially opened on 11 June 1988 by Prime Minister Bob Hawke, and the base is named in honour of former wartime prime minister John Curtin. As one of the RAAF's three bare bases, alongside Learmonth and Scherger, Curtin was conceived as part of a strategic shift toward defending Australia's northern approaches, and it has been fully activated for major exercises including Kangaroo '89 and '92, Pitch Black '91, and Exercise Northern Shield in 2016, on occasion expanding from a caretaker staff of around four personnel to a fully functioning air base hosting some 800 military personnel and fighter, strike and transport aircraft. From the late 1990s the base also operated as the Curtin Immigration Reception and Processing Centre, an Australian Government immigration detention facility, which closed in September 2002 before briefly reopening in April 2010. Scheduled civil flights between Perth and Derby via Curtin resumed in 2007 for the first time since 1992, but ceased again in February 2016. In 2016 and 2017 the Australian Government announced upgrades to the base worth A$100 to A$200 million, and the 2020 Force Structure Plan later allocated further funding, reported at around A$244 million, toward redevelopment of Curtin's facilities and infrastructure.
Curtin remains a bare base, maintained during peacetime by a small caretaker garrison drawn from No. 322 Expeditionary Combat Support Squadron, ready to be rapidly expanded to support flying operations during Defence exercises or deployments. It continues to function as a joint use aerodrome, combining this military role with civil airport access under lease to the Shire of Derby-West Kimberley. Given its status as an active military installation, pilots planning to operate there should expect that prior permission is required before any visit.
