Airlines of South Australia

On 1 July 1959, Ansett purchased Guinea Airways and rebranded it Airlines of South Australia (ASA) on 21 December 1959.

In 1980, a route sharing agreement was commenced with Rossair, and on 17 July 1981 Ansett reverted AASA back to the original name Airlines of South Australia.

However, ASA faced increasing competition through the late 1970s and early 1980s, and in 1985, Ansett announced that another subsidiary Kendell Airlines would progressively move onto South Australian routes.

In October 2003, Airnorth (based in Darwin, Northern Territory) purchased both Airlines of South Australia and Emu Airways (another small regional airline, based in Adelaide, operating from Adelaide to Kingscote) and merged the three companies into a single business entity called RegionalLink.

The participating airlines continued to trade in their local markets under their own names, the logos of which were featured on the fuselages of aircraft within the group.
