The 1981 Australian Sports Sedan Championship was a CAMS sanctioned national motor racing title for drivers of Sports Sedans complying with CAMS Group B regulations.
The Sports Sedan championship was discontinued from 1982 with the introduction of the Australian GT Championship, though sports sedans were still able to race with the GT cars, while some cars such as the Chevrolet Monza, Alfa Romeo Alfetta GTV and BMW 318i turbo were converted to GT specifications (the GT championship itself lasted only until 1985 before also being disbanded due to GT cars being outnumbered by sports sedans). Although there were minor sports sedan series run in various Australian states, the Australian Sports Sedan Championship would not return to the Australian calendar until 1991.
The 1981 championship was the last time legendary Australian driver / businessman Bob Jane raced. Driving his Pat Purcell built DeKon Chevy Monza to equal ninth in the series Jane, who had won the Bathurst 500 on four occasions in the 1960s, and had also won four Australian Touring Car Championships, retired from driving at the end of 1981 due to an ongoing back injury.
Tony Edmonson, the reigning ASSC, won his second title in a row 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 L Monza of Adelaide's John Briggs who finished second in the championship with Sydney's Phil Ward finishing third in his Penthouse sponsored Holden Monaro HQ. Both the Alfa Romeo and the Monza were built by the Adelaide-based K&A Engineering.

Rounds 5 & 9 were contested as single races and all other rounds were staged over two heats.
Championship points were awarded on a 9-6-4-3-2-1 basis to the top six placegetters in each round. Only the best nine round performances were counted towards each driver's championship total. For rounds run over two heats, round points were awarded on a 20-16-13-11-10-9-8-7-6-5-4-3-2-1 basis to the top 14 placegetters in each heat. The six drivers attaining the highest aggregate from the two heats were then awarded the championship points for that round. If more than one driver attained the same total, the relevant round placing was awarded to the driver who achieved the higher placing in the second heat.Note: The above results are based on the table published in Australian Motor Racing Year, 1981, Page 164 however additional positions below the top six have been calculated from race results listed in the same publication.
