I have had a car parked in my carport for 2 days. Have tried to find owner. Have contacted police and real estate agents about this car. Currently it is unregistered, but has an unregistered vehicle permit in windscreen. This car is preventing access for me to park and as a result, I have to park away from my unit and unable to park in my undercover car park. My question is: what can i do to regain use of my property (the car space)?
