hi JT et al,
thanks for all the advice and suggestions. i am in NSW, and not really familiar with all the rules and regulations mentioned so far; but i would have no problem going after strata or anybody else legally to defend my rights.
in my case, tenants initially refused to pay outright whilst being compensated, then they were happy to pay partly, but i do not feel it is fair. thus i decide that they should leave, and i plan to return back to apartment especially if work has not started, and no news whats over from anyone responsible.
the roof defect was a construction defect, and not wear and tear, so i know for a fact it is not covered by landlord insurance which i had.
my next step is to contact strata manager in charge and speak to her or him directly to find out what my options are.
