You likely have appointed a Strata Manager who will do most of this stuff for you – usually they will handle the Secretary, Chairman, and Treasurer roles and issue levy notices, help set the budgets, deal with prickly owner issues and other what-not that you pay them to do.
That is a big assumption. Many larger buildings have chairs, secretaries and treasurers as well as strata managers and many, many smaller blocks don’t have a strata manager at all.
And, yes, some strata schemes do delegate the office-bearers’ duties to the strata manager, but many don’t.
On the question of Secretaries’ specific duties Fair Trading’s Strata Living Guide says this:
• Secretary: arranges meetings by providing advance notice of them, prepares and distributes meeting agendas and minutes, and maintains the strata roll.
The NSW strata Act says:
The functions of a secretary of an owners corporation include the following—
(a) to prepare and distribute minutes of meetings of the owners corporation and submit a motion for confirmation of the minutes of any meeting of the owners corporation at the next such meeting,
(b) to give on behalf of the owners corporation and the strata committee of the owners corporation notices required to be given under this Act,
(c) to maintain the strata roll,
(d) to enable the inspection of documents on behalf of the owners corporation in accordance with this Act,
(e) to answer communications addressed to the owners corporation,
(f) to convene meetings of the strata committee and (apart from its first annual general meeting) of the owners corporation,
(g) to attend to matters of an administrative or secretarial nature in connection with the exercise of functions by the owners corporation or the strata committee of the owners corporation,
(h) any other functions conferred on the secretary under any other Act or law.
