MNS – on the basis of your posts here and elsewhere on FlatChat it’s obvious that you (at least) have a problem with your Strata Manager’s performance.
So in advance of the next General Meeting where you and like-minded Owners could bring him to heel, have a look at the website maintained by the peak industry body, in particular peruse their constitution and code-of-ethics under the “members” tab, and then give them a call to see if your Strata Manager or his Company is a member.
Hopefully he or his Company is a member, and the industry body can be your “plunger”.
