Ok just to clear up a couple of things posted here.
In NSW now you call the Magistrate Your Honour.
The camera does take two photos, one after the light is red to show the empty intersection and one when the thing is tripped so hopefully the first photo will show you stopped with your brake lights on.
You are probably going to be asking for a "Section 10" which means you are pleading guilty but that you are asking the Court to record no conviction because of x circumstances.
