fred11 – As far as I can tell there is no such thing as a Code of Conduct in the NSW legislation. The following may be of some assistance.
SSMA 2015
37 Duty of members of strata committee
It is the duty of each member of a strata committee of an owners corporation to carry out his or her functions for the benefit, so far as practicable, of the owners corporation and with due care and diligence.
Note : Section 260 provides protection from personal liability for members of strata committees who act in good faith.
The functions of the Secretary under this Act include the following:
(a) investigating and carrying out research into matters relating to or affecting strata schemes,
(b) investigating and attempting to resolve complaints and disputes relating to strata schemes and taking any action that the Secretary thinks appropriate,
(c) prosecuting any offence established by or under this Act,
(d) providing information to owners or occupiers of lots in strata schemes, owners corporations, lessors of leasehold strata schemes, strata managing agents and the public about this Act and the services provided by the Secretary and the Tribunal,
(e) investigating and reporting on any matters, or making inquiries in relation to any matters, referred to the Secretary by the Minister in connection with this Act.
