The 1961 Australian Grand Prix was a Formula Libre motor race held at the newly completed Mallala Race Circuit in South Australia on 9 October 1961. The race, which was Round 5 of the 1961 Australian Drivers' Championship, had 17 starters. Davison’s Australian Grand Prix victory would be the last for a domestically-based Australian until Frank Matich won the 1970 AGP at Warwick Farm in Sydney driving a McLaren M10B Formula 5000 car, although British-based Australian Jack Brabham had won the AGP in both 1963 and 1964.
