The 2002 Australian Formula 3 Championship was a CAMS sanctioned national motor racing title for drivers of Racing Cars complying with FIA Formula 3 regulations. Eligibility was restricted to cars constructed outside of Australia between 1 January 1995 and 31 December 2001. The title was contested over an eight round series with two races per round.
Points were awarded on a 20-15-12-10-8-6-4-3-2-1 basis to the first ten finishers in each race with an additional point awarded for both the fastest qualifying time for each race and the fastest lap of each race. An additional contest, the National Series, was run concurrently with the Australian Formula 3 Championship but was restricted to Level 2 cars, i.e. cars constructed within Australia and cars constructed outside of Australia between 1 January 1989 and 31 December 1994. Points were awarded in the same manner as for the Australian Formula 3 Championship.
