The fact that strata could make money off of the repairs is a scary thought.
By “strata” I assume you mean the strata manager here. Be careful with your terminology as that could trip you up in an NCAT case. There’s strata managing agent (strata manager), strata committee and strata scheme … all different.
You might do well to get some initial advice from one of our sponsors, like Strata Answers or Sachs Gerache lawyers, or someone more local to you.
