Just playing (attempting to?) devils advocate brickies. Have lived on the border for nearly 30 years and this has been an ongoing discussion here for all that time. It encompasses not just roads/ rego but all public facilities like pools /parks/libraries and the list goes on. I have a memory of a couple of local govt areas wanting to charge non residents for the use of their roads etc (can't remember where or result). Proposed congestion taxes in Sydney could be considered another form? I agree that the system can be manipulated for many reasons from cost to licence cancellation etc. If inclined i could register all my vehicles and licences in Vic and save a lot of money. I pay more to register my box trailer in NSW than I do for my 20 ft van in Vic.  As an aside both my Vic address and NSW address are on the Vic rego papers (garaged and postal) and vicroads were fine with that. I am just trying to point out the ridiculous situations created by state borders and the lack of action by all levels of government to resolve the issues. It affects a lot of people, including people like us on this forum who travel or live full time on the road. Bring on National rego!!
