After 23 years of no traffic offences I got a notice of having been detected for 68km/h in a 60 zone. I know NSW and Vic have a process where drivers can apply to be issued with a warning instead but on the back of the notice in FAQ no.4 it says:
"I have never received an infringement notice before. Can you show some leniency?
No. Speeding or failing to stop at a red light is considered to be a life endangering offence. There is no provision in Queensland for the issuing of a warning for camera detected offences on the basis of prior driving record."
You could contest the fine in court, but no you can't apply for leniency.
I doubt you'd be successful in getting a warning if you contested, however.
