The new ACT Unit Title (Management) Act 2011 has a Code of Conduct for ECs and another for Managing Agents included at the end. If NSW doesn't have anything like this (I don't know) an OC could decide to adopt its words in any case I would expect. It might be a non-specific, non-confrontational way to put concerns on the table. Also, when the Act was tabled, Teys lawyers published a set of notes on each of the code of conduct points. I expect you request a set from them.
