In order to comply with Incorporated Societies Law and to facilitate communications generally, our Rules require Districts and Branches to provide the names and addresses of office bearers to the Management Committee annually and as changes occur. The exact Rules requirements can be found here (Clause 9.6).
This can be achieved by sending an email to the General Secretary.
While the Rules only require names and addresses, communications by email are now generally more common, so the addition of a contact email address is appropriate.
