there is also just a few comments about us paying for up keep of the roads.
Rego does NOT pay for roads. Rates and taxes do. Taxes like GST and alcohol and tobacco taxes. Yes fuel excise too. So when you see me riding down the road on my bike with the expensive wheels and me in my lycra and helmet on, that is all paying for our roads. If you are in a car the GST on that and the fuel excise also pays for our roads. If you pay income tax, that also pays for our roads. If you own a house and pay rates, those also pay for our roads. In a round about way your rego contributes to the pot of money that all government expenses come out of (including all of the administration and other expenses of registration), but if you looked at registration as a stand-alone item it is not profitable. your license only means that some time in the past, you managed to pass a driving test.
