Nestled along the stunning South Coast of New South Wales, Seven Mile Beach holds a remarkable place in Australia’s motor racing history. Known as the Gerringong Speedway, this iconic stretch of sand was the site of thrilling speed trials and racing events in the 1920s and 1930s, drawing thousands of spectators eager to witness record-breaking feats.

Breaking the 100mph Barrier

In March 1925, the Royal Automobile Club speed trials attracted 2,000 spectators, all hoping to see history in the making. Their wish came true on October 7, 1925, when Don Harkness shattered the 100mph barrier, reaching 107.75mph in his Hispano-Suiza, V8 Minerva.

Pushing the Limits: The 200mph Attempt

Not content with just one record, Don Harkness and Norman ‘Wizard’ Smith attempted to break the 200mph barrier on December 1, 1929, using a Cadillac fitted with a Rolls Royce aeronautical engine. Unfortunately, rough surf and uneven sand caused the attempt to fail, with the car briefly sailing 40 feet above the beach after hitting a bump.

A Hub for Racing Enthusiasts

Seven Mile Beach became a racing hotspot, attracting numerous car and motorcycle clubs. In 1923, the Goulburn Motorcycle Club raced along the beach, reaching speeds of 75mph on a 4-cylinder Henderson motorbike. Before motor vehicles took over, horse racing events had been held here since the 1860s.

A Historic Aviation First

Beyond racing, Seven Mile Beach was the runway for the first commercial flight between Australia and New Zealand in 1933. Piloted by Sir Charles Kingsford-Smith, the flight took off at 2:30 am, with cars lined along the beach, their headlights illuminating the makeshift runway. Thousands gathered to witness this groundbreaking aviation milestone.

A Legacy in Australian Motorsport

Gerringong Speedway remains an essential part of Australia’s motorsport and aviation history. From record-breaking races to pioneering flights, Seven Mile Beach was more than just a scenic coastline—it was a place where history was made.
