This is a massively complicated situation but much of it would be resolved, I reckon, with the removal of the strata management firm, something that can be done through orders at VCAT.
If you want to take this on yourself, then start HERE. But, I think your best bet would be to find a reliable ally within the ethnic community, get them to rally support by telling owners how they are being ripped off, then collectively hire a strata lawyer to sort this out and get costs from the culprits when you have done so.
Or just go and talk to a specialist strata lawyer.
