Have you received one in the mail?
A while back I got pulled over for a traffic offence. Minor matter, guilty, but is irrelevant to the question.
The police officer took my licence went back to his car, did some stuff and came back and said the fine would be in the mail in 'a couple of weeks'.
I waited for a few weeks and finally went and looked at my Service NSW App. and there was a fine in the fines section. Still no mailed version arrived. No apparent notification of it being received by email (I went and searched incl spam) or on the app. Our address hasn't changed for years and have received mail previously.
Have you received a fine in the mail lately, or just on the app? Did you get a notification? Makes me wonder if I got pinged by a camera if I didn't actively look for the fine id end up being past due and get an additional fee.
In NSW. Fixed speed camera - got a fine delivered by mail. I'd guess about a year ago.
