yeah i tried this a few year back, paid a buck extra, didnt work, didnt get my buck back either..lol ..I did have unpaid fines from over 10 years ago and to my knowledge the points never came off, I also received a red light camera in QLD which I paid but never lost any points..
Whats even odder is I got pulled over a while ago for allegedly being on my phone (which I wasnt), he checked my license out and says that I have 13 demerit points he also stated I had no loss of license , even he didnt know why.. I later checked with Vicroads and their system says otherwise..
He was then nice enough to not fine me for not being on my phone, which was nice of him
there is no doubt many loopholes in the system though, but you will usually only find them by accident and they are constantly being rectified
