Sorry pal, maybe in Australia they issue tickets to police cars, fire-fighters' trucks and the like, but for the last four years I have been involved in automation for Police Departments and such lists exist.
Obviously, they are not named "don't issue a ticket to the whealty bastard," they are named "Official Vehicles" and many politicians get their "official" vehicles listed there including cars of whealty supporters.
Now, my very own experience. I don't work directly for any PD given that I am an outside contractor but some friend got me some decals for my windshield. Two days ago, by being distracted, I ran a red light while doing a U-turn while policemen were stationed at the intersection. One look at the decals and they assumed I am an undercover officer running after some bastard; they waved me on.
Even if they had made me stop, they would have to call Central to report the incident before issuing a ticket (SOP) and I would claim a "Code 3" (emergency) and my friends at Central would have supported me.
So you see, even if you are not a whealty bastard, you can get away with it if you know the right people.
