Thank you for the information and the links.

Knowing that the Australian police vehicles were not (all) specially built for law enforcement is quite helpful. I'll have a much less difficult time tracking down the data I need so that I can include some Australian police vehicles in the piece I'm writing.

As far as the the markings and paint schemes, I had assumed that was the case from what research material I have found. Thanks for the confirmation.
