• Tomlinson completed 24 laps in 1 hour, 13 minutes, and 2 seconds, averaging just under 58 mph despite mechanical limitations.
• The race attracted over 15,000 spectators, many traveling by train, highlighting the event’s national significance.

How It Works

The 1938 Phillip Island Grand Prix operated as a handicap-style time trial, where cars started at intervals based on their expected performance. This format allowed diverse vehicle types to compete fairly and increased spectator engagement throughout the day.

• Handicap Start: Cars were seeded by engine size and modifications, with slower vehicles starting earlier to create a dramatic finish.
• MG T (Supercharged): Allan Tomlinson’s car featured a modified 750cc inline-four with a Roots-type supercharger, boosting output to ~70 hp.
• Lap Distance: Each lap measured 2.8 miles (4.5 km), combining public roads like Churchill Road and Landers Lane into a continuous circuit.
• Timekeeping: Manual stopwatches were used at timing points, with officials recording lap times to determine overall standings.
• Vehicle Classes: Entries were divided by engine displacement, with categories for under 1,100cc, 1,500cc, and over 1,500cc engines.
• Prize Structure: The winner received a silver trophy and cash prize, while class winners were awarded medals and recognition in motoring journals.
