The poster seems to primary want Strata Police. Or some authority that will investigate their issues and take appropriate intervening action.
But there are no Strata Police. The only authority that can enforce strata law in VIC is the legal system. That’s the Tribunals and the Courts.
All of the rest are just advice bodies or mediation bodies that have no actual authority.
It’s nothing new. It’s been that way since the start of strata.
While I sympathise with the poster, there comes a time when one has to decide: Seek professional legal advice and or take the matter to the Tribunal.
Looking for an authority to intervene in your issues is not going to happen. There aren’t any except for the legal system.
The most you can get is advice and non-binding, non-compulsory mediation.
