Most insurance companies we deal with give you a complete new car no questions asked if they are written off, and are less than a year old...so hopefully that will happen for you, but more importantly you are okay and noone else was in the car (am assuming)
I would like to lobby the RTA to make third party property at least manditury like the greenslips are when rego is due, as too many deadbeats get around in bombs uninsured and a lot of the time unregistered as well...

How annoying as you will be down a car until they sort something out for you...
