(7) If the road does not have a continuous dividing line or a dividing strip, the driver must position the vehicle so there is at least 3 metres of the road alongside the vehicle that is clear for other vehicles to pass, unless otherwise indicated by information on or with a parking control sign.

(8) The driver must position the vehicle so the vehicle does not unreasonably obstruct the path of other vehicles or pedestrians.
Now if I only my neighbours at my old house knew that one. It was so bad that I almost photocopied that section of the road rules and did a letter box drop. We lived in a dead end street, so if we could not drive up it then could not get to our house. Councils only solution was for us to apply to have parking banned on one side of the road, which would have disadvantaged the whole street. I wanted them to book the repeat offenders, but they can only book if they know which was the car to cause the blockage (ie the second car to park).
