The new outright lap record of 2:12.6 set by New Zealand’s Chris Amon in a Ferrari P4 sports car at the final meeting was, with an average lap speed of 122.2 mph (196.62 km/h), the fastest lap record for any Australian motor racing circuit and would remain so until the opening of the new Calder Park Thunderdome in Melbourne in 1987, though unlike Longford which is a road circuit, the Thunderdome is a 1 kilometers high-banked (24° in the turns) quad-oval speedway.
