HOCA has approximately 60 members from mostly NSW, as well as some interstate members who are the proud owners of about 75 Hillmans and a number of Commer trucks. Vehicles range from the early 1930's to the mid 1970's. Many are beautifully restored, some are in original condition and others are in the process of being restored. Some vehicles are on conditional registration, while others are fully registered. Whatever vintage or condition, each vehicle is very much enjoyed by its owner and proudly displayed whenever possible.
