Well this has kicked up a hornets nest.
I think the simple points are a new owner wanted the names and contact details of the committee.
The SM should have sent him their names and postal addresses straight away. There is no reason to withhold what any owner is entitled to. But emails and phone numbers should only be sent if the member is willing to share them. Yes a full strata search would have them in it, as all records are available.
Personally I think that emails should be part of the contact details on strata rolls as that’s the way most people correspond. But it was not included in the act when it was changed in 2015.
The remainder as to the workings of the committee or the owners corporation. Will not be known unless the original poster sends an update.
