The regulations for the championship were published by the Confederation of Australian Motor Sport under the name Australian Formula 1 Championship,[1] and the Official Souvenir Program for the 1978 Australian Grand Prix listed the race as "Round 2, 1978 Australian Formula One Championship".[5] However it was reported in the Australian Competition Yearbook (Number 8) as the Australian Drivers' Championship[3] and is recognized by CAMS as the 1978 Australian Drivers' Championship[2] and the latter term has been used for this article.
