Quite an expensive and upmarket motorcycle and sidecar for its time - the Model 55 bits means it has twin exhausts on a single cylinder motor, all the rage at the time, and it also has factory fitted newfangled electric lighting. Electric lighting wasn't new by then, but lights were still an optional extra, you paid more for them. Nortons were famous for their racing successes, so this was a decidely dashing outfit for the times, a real sports model.
Looks fairly new in the second pic. And that Imperial Confectionary Packing Works in the background should be findable. Bigger libraries in your area may have copies of Sands Directories for the early 1930s - these have directories of commercial premises. Its likely to be in Melbourne, or perhaps (maybe) a bigger country town, and should be listed. Perhaps in the phone books of the time too, also in bigger libraries. May even still exist, if its not on prime industrial land (which is likely to have been redeveloped).
Great pics.
