There is quite a deal of confusion about who controls Fixed Speed Camera. Some people thinks it is RMS(RTA). Others think the Police.
The reality is that Fixed Speed Cameras are managed by the Centre for Road Safety. This is a unity of the NSW Department of Transport under the direction of Minister Gladys Berijiklian.
The Centre for Road Safety has an interesting website: Centre for Road Safety
On the Centre’s site you can nominate a site for a speed camera.
