I once held a Victorian registration in Melbourne and then when I moved to NSW my registration wasn't recognised. Coming from NZ where registration is nationwide I thought that was absurd.

If Australia is going to remedy this then that sounds like a good move. It does mean however that the government will lose some revenue in licensing fees and of course the lost revenue will have to be made up somewhere else ( think licensing fee hikes for sparkies )

As for the implementation of this system; Does Australia have one electricity legislation for the whole country or does each state have its own act ?
