My one experience with SCA is dismal.
The OC sacked the strata manager, a well known Sydney company.
We then lodged a complaint with SCA. It was supported by good proof. They gave the complaint to the strata manager (that’s reasonable ).
It took a long time to get a reply, after which SCA replied that no breaches of their rules had occurred. However they would not release to the OC the response from the strata manager, nor the minutes where the SCA board reviewed the case.
No justice there.
