From the same year AF2 cars were eligible to compete alongside the 2½ litre Australian National Formula cars in the Australian Drivers' Championship for the first time. The Australian Formula 2 Championship was reintroduced for 1969 and was contested concurrently with the final round of the 1969 Australian Drivers' Championship.
