Caboolture is an urban centre or satellite city approximately 44 kilometres (27 mi) north of Brisbane, the state capital of Queensland, Australia. Caboolture is considered to be the northernmost urban area of the greater Brisbane metropolitan region within South East Queensland, and it marks the end of the Brisbane suburban commuter railway service along the North Coast railway line . As at 30 June 2010, Caboolture had an estimated population of 46,882
Formerly a small dairy town, the location of Caboolture on the corridor between Brisbane and the Sunshine Coast resulted in an influx of residents in the 1970s and 1980s. The three main factors in this expansion were the electrification of the railway line to Brisbane, enabling travel to the Brisbane CBD in less than an hour, the development of the Bruce Highway to freeway (motorway) standard, and the availability of cheap land.
In common with many outer areas of Brisbane, the Caboolture Shire Council encouraged the development of low-cost housing areas that were affordable compared to established areas in Brisbane. This policy resulted in estates of small inexpensive houses on small blocks. At the same time, the Council allowed the subdivision of rural land into 'acreage' housing estates consisting of between 3⁄4-acre (3,035 m2) to 2-and-5-acre (8,100 and 20,200 m2) blocks.
Caboolture is a regional transport hub. With its connections across the Great Dividing Range via the D'Aguilar Hwy, easy highway access to Brisbane and the Sunshine Coast via the Bruce Highway, and the Bribie Island Road to Bribie Island, it is a focal point for road traffic.
Caboolture railway station is the terminus for QR Citytrain's Caboolture railway line, as well as being a major stop on theNorth Coast railway line. Citytrain operates regular services to Brisbane, in addition to interurban services to Nambour and Gympie, with significant expansion of services north of Caboolture planned over the next decade. The area is serviced by two bus companies, Caboolture Bus Lines and the larger Kangaroo Bus Lines.
Caboolture also contains its own airfield, which primarily services general and recreational aviation. Visiting aircraft are able to operate into the Caboolture airstrip, which is under the operational control of the Caboolture Aero Club Inc. Additionally the airport is home to a number of aviation enterprises and attractions - amongst them, the Caboolture Warplane Museum (with operational P51 Mustang, CAC Wirraway and CAC Winjeel aircraft), skydiving club, and the Beaufort Restoration group (a group of volunteers restorating an Australian-built DAP Beaufort Mark VII Bomber).
