Yeah, in Oz, it's each State/Territory that controls the rego plates & registration/insurance etc for the entire State/Territory, not the Local Government (we tend to call them Councils, and here, they aren't allowed to run 'Police Forces' or impose taxes - just 'rates' for services like local street maintenance, garbage collection, sewer, etc), but we don't have quite so many States as you lot do, and ours have managed to agree between themselves to sharing access to each other's data-bases. So while it took a bit of a while to get to this stage, they all did eventually agree to get rid of the need for yearly stickers &/or re-issuing plates etc - it's all in their data-bases!
Mind you, in the couple of years during which the transition occurred in each State/Territory in turn, it was a bit of a pain for those of us who regularly travelled interstate, especially if we originated in one of the first States/Territories to get rid of the Stickers - the number of times I got stopped by the Cops while travelling interstate simply because they couldn't see a valid sticker rapidly became very much
NOT Funny; but at least I was aware of the chance, so I always carried a paper copy of all my current rego & insurance details (still do!

) and I didn't ever get held for long over it - others weren't quite so lucky!!
Still, it only took a couple of years before everyone/all the States & Territories were working from the same page; and these days, sharing of that info is almost seamless - you can get pinged for driving an unregistered/uninsured vehicle from any State on the roads in any other State by any Police Car, or if you're on major roads or Highways, the cameras will get you even without you getting pulled over for it, at least initially!! However, if you move house/residency across States/Territories, you still hafta change your license and residency details, and while those of us with more than just a standard 'car license' can get what's called a '
National Driver's License', if we move from saaay, New South Wales to South Oz (as I did a while back) then we still hafta front up to surrender and change our NSW issued 'National Heavy Vehicle Driver's License' to a South Oz issued 'National Heavy Vehicle Driver's License'!!
