Going by the fact that I work for the Dept of Transport in WA, due to privacy laws & regulations, no one is allowed to obtain any information regarding someones driver's licence, vehicle licence or any other confidential information.
If we were to give out information regard someone's driver licence or vehicle to a third party, that would be a breach of the privacy laws & regulations.
So, in essence, I'm pretty sure it would be the same for the eastern states. So, no they would not be able to obtain information from the RTA about your driver licence and/or vehicle/s.
