yep its illegal to bend or cut a number plate. Its plain and simple against the law and I doubt that going and talking to the head officer of the station you were booked at is going to do anything about it either, they never want to hear about it as its their employee. If i were you id winge a little (send a letter to the police commisioner of QLD), send the fine back saying your contesting it, then contest it if it ever goes to court as it costs you nothing really. Then if you lose, which you probably will, make up brackets to try and fit the number plate out from the normal slot or you may have to drill holes into the bar to put it on....That or get personalies plates...its b.s but the police will just say it was your choice to buy a non australian car, bring it up to standards or wear the fines. I think its an absolute F*CKING LOAD OF SH*T and when I am finished my degree if I ever get caught for something stupid like this I will F*CK over whoever I can to get the ruled change as legal costs will be "free". Sorry to hear about it, keep us updated on progress.
