I assume you mean the Act (Strata Schemes Management Act) and not the ACT.
I know of only a couple of instances where this has occurred in Sydney and that has been because of rogue parking on common property access roads that was potentially going to block access by emergency vehicles.
Councils will not manage parking in covered parking areas because of safety concerns and are reluctant to go into other schemes because of the cost-benefit issues. The occasional rogue parker in a strata scheme, plus the hassle of ticketing every breach – such as people parking slightly over their lines, which they are obliged to do – means it’s not worth their time and energy.
If anyone knows of a scheme where this is working effectively, please let us know. But to be honest, smart and diligent use of exisiting laws and by-laws mean this can all be better handled in-house.
