aussiefan has it. For me, it was moving around rural NSW & Qld with visits back to parents in Vic; also done it decades later in a similar fashion. I have yet to discover any bureaucratic system, private or government, which can cater for such circumstances. If you tick their individual procedural boxes they are happy, never mind that fact the information supplied is utterly fabricated. A national licence (with all it's endorsements for car, motorcycle, tractor, heavy vehicle, boat etc) would make perfect sense. What about Australian-based ships crews who travel the world and are away months at a time? They have a similar problem no doubt. What about defence personnel?
Passports don't have residential addresses yet they are regularly requested as ID. I am often embarrassed by this nation's stupidity.
Ostrailyer, yer standing in it.
