I agree that it does look like "old". Unfortunately I had to lower the resolution to post it on the site.
Yes we do get "vintage" plates (which also say QLD) once the vehicle reaches 30 years old but there are some restrictions in use (ceremonial, parades. club rides. charitable events, servicing and testing, family events ) so maybe not appropriate for a bike you just want to ride. I will be putting my 350 Four on vintage plates when we finally get it together.
