The 1931 Australian Grand Prix was a motor race held at the Phillip Island Circuit in Victoria, Australia on 23 March 1931.[1] The race, which was the fourth Australian Grand Prix and the fourth to be held at Phillip Island, had 19 entries[1] and 14 starters.[2] It was organised by the Victorian Light Car Club.[1]
The race was staged using a handicap format with the first car starting 35 minutes before the two "Scratch" cars.[1] Prize money was paid for both handicap and overall results[1] with the principle prize of £100 awarded to the fastest car to complete the distance.[3]
Carl Junker was awarded the Grand Prix win,[4] having set the fastest time driving a Bugatti Type 39.[1] The Handicap Section was won by Cyril Dickason,[4] driving an Austin 7.[1]
