We have no national ID in Australia and the federal government has limited constitutional powers. We have tax file numbers and medicare numbers but they are only used for tax or medical payments and for nothing else.

Like the US it is a federal system and states have constitutional authority over road rules, registration and licensing and can do their own thing. Every state has its own websites and apps for these things. Half our states do not have digital licences yet but some of them will be ahead in other areas. I suspect if we had to wait for something national to happen the less progressive states would hold us all back.
