G'day mate. Nice replica indeed. And welcome to the forum.
I agree the addition of the number plate would really set the model off. Having done NSW and Vic plates before, I know that the relevant Government Motoring Authority for both those States have websites with the ability to design a custom numberplate then preview it. You can then save the image, resize and print. Not sure about Qld though. With NSW you cannot preview a plate that already exists (i.e. your own) but with some imagination and copy/paste it is easy to make your own.
