Seremify, I feel your pain.
Was a couple of months ago, but I got done doing 54km/h in a School Zone. ow the catch was, it was a fixed camera at Bateau Bay. This school zone camera had different operating times to all others on the Central Coast, starting half an hour earlier in the afternoons.
I got clocked on a busy Entrance Road, and the only warning I had was the colour of the numbers of the operating hours were red instead of black. I was driving mums car, and luckily I only had to pay the actual $75 fine. But it is 3 demerit points as well.
But that Bateau Bay camera has had many a court case come from it in recent time. It has been proven to be quite a revenue raiser.
