I think the first thing I would do is ask the strata manager to provide in writing on what grounds thery shut you down. The law is pretty clear on this and given the risks associated with the gang wars over discount cigarettes and vapes, you are right to be concerned.
Why would the strata manager block this? Maybe they are cozy with the owner of the property who might lose a valuable tenant if they have to pay for the increase in levies.
Anybody have a valid reason why the strata manager may be blocking this?
