I have a few a cars on Qld historic rego and some on Vic. The changes to the Vic system is a step in the right direction, but since I drive the cars in Sydney, I have never been stopped. The Qld system is more expensive and more restrictive, but as stated, you can have personalised plates, so it does make it less obvious. I have never been asked by my insurance company if they are registered as normal or historic.
