The 1980 Australian Sports Car Championship was a CAMS sanctioned Australian motor racing title open to Group D Production Sports Cars.[1] The title, which was the twelfth Australian Sports Car Championship,[2] was won by Allan Moffat, driving a Porsche 930 Turbo.[3]
The championship was contested over a five-round series with two heats per round.[3]

Cars competed in two engine displacement classes:[1]
Round results were determined by allocating points on a 20-16-13-11-10-9-8-7-6-5-4-3-2-1 basis for the top fourteen places in each heat.[1] Where drivers attained the same number of points, the placings achieved in the second heat were used to determine the round placing.[1]
Actual championship points were then awarded on a 4-3-2-1 basis for the first four outright places at each round, regardless of class.[1] Additionally, championship points were awarded on a 9-6-4-3-2-1 basis for the first six places in each class at each round.[1]
The top nine championship placings were as follows:
