Various solutions about bollards and other methods re changing fobs, adding key pads etc etc have been discussed to stop illegal parking but not acted on.
So it actually has been discussed by the committee? Meaning that the committee has not ignored the matter but has not come up with a solution to your satisfaction?
Considering that tens of thousands of stratas around the nation have not been able to solve this issue either, what exactly do you expect your committee and NCAT to do? I suggest you address that question before heading off to NCAT.
The usual “solutions” for this matter (visitor parking) are either unworkable, illegal, temporary or not affordable. The fault is not so much with the strata committee. The fault is the weak legislation that has prevented stratas from being able to do much.
Sure, if you have a strata that is able to pay for 24/7 on-site security staff, you might be able to do something. Sure, if your council is one of a few in Australia that is willing to include your visitor parking in their parking enforcement area, you might be able to do something. Both are not free of course.
Else all other solutions are pretty much unworkable, illegal, temporary or not affordable.
Tens of thousands of stratas wish they weren’t. Unfortunately.
