1973 Australian Formula 2 Championship

The 1973 Australian Formula 2 Championship was a CAMS sanctioned motor racing title open to Australian Formula 2 racing cars. It was the seventh Australian Formula 2 Championship to be awarded by CAMS.

The championship was dominated by multiple-championship winning driver Leo Geoghegan, who scored a perfect 54 points from six round wins over the course of the season.

The championship was contested over a seven round series with one race per round.

Championship points were awarded on a 9-6-4-3-2-1 basis to the first six eligible finishers at each round. Only holders of a General Competition License issued by CAMS were eligible for points and each driver could retain points only from his/her best six round results.
