The 1930 Australian Grand Prix was a motor race held at the Phillip Island circuit in Victoria, Australia on 24 March 1930. The race, which was organised by the Light Car Club of Victoria, was the third Australian Grand Prix and the third held at Phillip Island. It was staged as a scratch race with the Class A cars starting first, followed by the Class B entries three minutes later and the Class C cars a further three minutes after that. The Grand Prix title was awarded to the entry recording the fastest time for the race. Of the 22 cars which started the race, nine complete the race distance within the 4½ hour time limit, one was still running at that time and the other twelve withdrew.
The race was won by Bill Thompson driving a Bugatti Type 37A.
