Hi, I have just received a $151 infringement notice for exceeding the speed limit doing 68 k/h in a 60 zone. The camera was on Jubilee Tce, Bardon at the bottom of a long steep hill. If I contest this in court as being inequitable, opportunistic and exploitative, what are my chances and could I be liable for further costs? I've received 3 identical speeding fines in this location in the last 3 years. Thanks in advance.
