In the 1950s my Dad attended the bike races at the old Mt Druitt circuit. The circuit was used from 1948 to 1958. Spectator attendance often exceeding 15,000 and was believed to be one of the best motor racing circuits in the country. The course was 3.6 kms long and situated on what is now Whalan Reserve, the Mt Druitt Industrial Area and Madang Avenue Primary School. NSW. Australia.
My Dad took these photos.
If you know who the riders are please let me know.
