The sole SC1 was designed and built by Southern Cross Aviation and flown in 1961. It was intended to be a four-seat touring and training aircraft powered by a 180 h.p. Lycoming O-360. After 25 hours testing it was decided that it could not realistically compete with such as Cessna. It was stored and acquired by the Moorabbin-based museum for display for a period, before retuning to its Toowoomba Queensland birthplace. The "VH-SCA" markings were unofficial.
