prt1000 – I assume you’re in Sydney CBD, and you’ll find your answer HERE.
Re towing – it’s a long story, but in NSW, if the Owners Corporation (O/C) has a Special By-Law in place that provides for the towing of illegally parked vehicles, then it’s accepted that Owners (as members of the O/C) have implied acceptance and knowledge of that, and consequently their vehicles can be towed.
Sadly, tenants and outsiders don’t have that implied acceptance and knowledge of that Special By-Law (or of any other), and so their vehicles cannot be legally towed.
Don’t know what applies in the sunshine state; you there KWP?
