Maroubra Speedway, officially known as Olympia Motor Speedway was a motor racing venue in the Sydney suburb of Maroubra, New South Wales, Australia and was reported to have had a capacity of 70,000. Opening in December 1925 the 1 mile banked concrete bowl was the scene of some large and successful race meetings before a decline in attendances saw the track close in 1927, but reopened many times in the 1930s. Despite the banking being too steep to walk up it was still not enough for the speeds achieved, and four competitors lost their lives going over the top of banking.
