You have other issues aired in the Forum and two of them boil down to the same thing – your strata manager and/or committee doesn’t want to enforce your by-laws. That’s probably becasue your committee doesn’t want to do anything.
It sounds like it’s time you sat down with your chair and strata manager and asked them that age-old strata question – do you want to do this the hard way or the easy way? They aren’t going to save money by not pursuing by-law breachers … because if they do, you are going to pursue them (the committee) at NCAT.
So maybe it’s time they fulfilled their legal obligations … or got out of the way and let someone who’s prepared to manage the scheme properly take over.
