Roads here aren’t really paid for by motorists at all, it all comes out of general revenue (local rates, state revenue and commonwealth grants where appropriate). Fuel tax is just another tax, same as the Medicare levy doesn’t actually fund Medicare. The move to electric vehicles and bicycles does create a revenue shortfall, but that’s all it is - not any kind of structural issue that needs clever new thinking. Implement a per/km tax on cars or just whack up GST, it doesn’t matter.
