1981 Australian Sports Sedan Championship

Reigning champion Tony Edmonson, won his second consequtive title in the Don Elliot-owned Alfa Romeo Alfetta GTV, this time fitted with an ex-Formula 5000 5.0L Chevrolet V8 engine instead of the Repco Holden V8 used in 1980.

His closest competition came from the 6.0 litre Chevrolet Monza of Adelaide's John Briggs, who finished second, with Sydney's Phil Ward third in his Penthouse sponsored Holden Monaro HQ.

The championship was the last for Australian driver / businessman Bob Jane, who drove his Pat Purcell-built Chevrolet Monza to equal ninth in the series.

Championship points were awarded on a 9–6–4–3–2–1 basis to the top six placegetters in each round.

The six drivers attaining the highest aggregate from the two heats were then awarded the championship points for that round.
