From asking around it seems that mostly, if not only strata managers who are part of the PICA group are doing this. Strata Choice, for instance, say adjusting to new laws is just part of their job and they are not charging schemes for that.
The charges seem to vary and I suspect they are related to the number of units in the scheme. If anyone has any figures – number of units v charges imposed, let’s have ’em. Post them here or email them to mail@flatchat.com.au – either is good.
