Importing any vehicle into Aus is made extra difficult/near impossible by the asbestos import bans........you would need to strip the vehicle completely ,and have the every part cleaned,stripped then inspected.............including wiring ,paint,under body coating.....and the obvious brakes,clutch,and gaskets............then the whole inspection needs to be done again by a accredited (to Customs) inspector on arrival here......in short....unless its a Rolls Royce Silver Ghost....forget it.
