This sounds very like a criminal case of gaining financial benefit by deception (or whatever the legal jargon is).
You need to talk to a specialist strata lawyer immediately about getting the required ruling from the CTTT to stop this planning procedure, get all your documents back from the strata manager and get the police involved.
You're right. This is serious. And once the strata manager has been charged and convicted you can broadcast their name far and wide with impunity … but not before.
Call a lawyer now.
