It's not an abandoned car. Depending who you call in council, you get different answers. One said to request a warden within the hour if the car is there (although they came the next day when it wasn't). Another said they were too busy and said unless it was illegally park, they can't do anything.
Coincidentally, right after I posted this, the parking warden was seen ticketing the car. 2 fines to surprise the owner in the morning. I guess council actually did something this time!
If the owner writes a nice letter to the council, they will get let off those fines. I have once been, once before, where I hadn't released a WOF had lapsed on a family members car that I was using while I was overseas.
But I think you only get to do the above once, So the car owner will need to bring the car into compliance (or park it on private land) to avoid future fines. They aren't cheap fines. $200 each for No WOF and No Rego.
