Westernair was its trading name. They started off in Charleville in 1960's. It was owned in majority by Bryce Killen who also owned a majority of Helicopter Utilities. Local graziers had minority share holdings. It s colour scheme was red markings on a basically white fuselage. It's business was supporting fledgling oil survey and drilling in SW Qld and MoombaGidgealpa area of SA as well as freight runs, cattle buyer charters and general air taxi work.
In the late 60's it moved headquarters to Brisbane Eagle Farm. Other aircraft were WAB, piper Aztec, WAC, Cessna 205, WAV, Cessna 185, RHT, Cessna 210, plus other aircraft seconded in from Helicopter Utilities. A Beagle twin registration unrecalled was obtained to commence Regulation 203 ( commuter) runs to Eidsvold, Biloela, Theodore etc, in approx 1968. A lot of the work for WAN and WAB out of BNE was taking executives and engineers etc to the budding open cut coal mines of central Qld.
In the late 60's a single engine aircraft was temporarily based in Springsure mainly for aerial buffet grass seeding. In the same timeframe Westernair took over the Rex ( as in Rex Cessna dealer) operation in Longreach which was a one man maintenance operation with the occasional aircraft based there.
