Fight4 justice
you are perpetuating a common misconception amongst strata dwellers.
when you take legal action , you are taking it against the owners corporation. The strata manager just does the bidding of the owners.
The resources of the other side to fight are limited. For example the owners need a special resolution to engage lawyers if the cost is above $3000.
In your case you can represent yourself at NCAT and the OC may not use a lawyer in NCAT unless the court agrees .
In any case, you’re addressing the wrong people. You should be directing your complaints to the committee. They are required to at least respond to your complaints. If it’s a matter of a lack of maintenance of common property, you only have to wait 2 months before going to NCAT. In this case you are certain to win, if the committee does not comply prior.
