National Jet Systems (NJS) was established in 1989 and started operations on 1 July 1990. It soon commenced scheduled operations on behalf of Australian Airlines, mainly to tourist destinations in northern Australia, operating a fleet of BAe 146 aircraft under the Airlink brand. After Australian Airlines was taken over by Qantas it continued these operations, and in 2005 commenced operating Boeing 717 aircraft, the operation being rebranded as QantasLink at the same time. The services on behalf of QantasLink are contracted until 2018. An additional base, located in Brisbane, was opened in early 2012.
NJS is owned by Cobham plc. Cobham Aviation Services in Australia operates different business units. Regional Services, also known as National Jet Express, or JetEx, conducts scheduled closed charter flights on its "regional network" and freight services on behalf of Australian air Express (AaE).
