I've seen speed camera shots from the front and back.
My plate is starting to fade quite badly as well, front one, and a mates was so faded it was practically illegible. Apparently they'll pick you up on that as a violation now also precisely because it can't be read by the cameras.
My wife got stopped and fined the other day for no front plate on my little ute. I'd removed it to swap bumpers and never got around to putting it back. To add insult to injury the cop said if it had been me driving he wouldn't have bothered because he can't speak English.
