Hi Jeff
This is not only normal but a sign that your EC is working properly to look after the building. There is no new building in Sydmney that doesn't have defects so be happy they are doing something about it.
By the way, I don't normally do this but Teys Lawyers have been piloting a new scheme that a) gets defects fixed and b) gets it done with the minimum of stress heartache and conflict.
Once you get setled in, suggest the EC talks to them.
