fighting parking infringements (updated....help!)

[dingo]

I just went back to my parked car about 15mins ago and saw a parking ticket under the windshield wiper. It was in a free parking zone (for 1hr) and I had only been there for about 20mins.....so I was shocked and seeing red!!! :x
I didn't read the ticket properly at first so I didn't see what it was really for, so I hunted down the %$#$ who gave it too me and asked him what it was for. He told me I was facing in the wrong direction (its parallel bays along side the road), and said it was a hazard for oncoming cars.....BULLSHIT.
However I noticed that on the ticket he had put the wrong rego number....he switched the '8' and the '0'....so I think I can get away with it. IF I don't pay and they come looking for me they'll never match it to me since that isn't my rego number.....HAHA.
Anyone have any similar experience and can tell me whether I am right in assuming this?
