If you are in NSW, a quorum is one quarter of owners entitled to vote, ttending in person or by proxy. But it’s not a simple as a head (and proxy) count. All the proxies have to be on the prescribed form and all the people voting have to be up[ to date with their levies.
Even then, it’s not as simple as that because you can count unit entitlements instead of simple votes. and een if that doesn’t get you over the line, all you have to do is hold the AGM again exactly seven days later and whoever turns up for the rerun forms the quorum.
This is what the Act says:
There is a quorum for considering and voting on such a motion or at such an election only if:
(a) at least one-quarter of the number of persons entitled to vote on the motion or at the election is present, either personally or by duly appointed proxy, or
(b) at least one-quarter of the aggregate unit entitlement of the strata scheme is represented by the persons who are present and entitled to vote on the motion or at the election, either personally or by duly appointed proxy.
THEN
(4) If a quorum, as provided by subclause (2), is not present within the next half-hour after the relevant motion or business arises for consideration at the meeting, the meeting stands adjourned for at least 7 days.
(5) If a quorum, as provided by subclause (2), is not present within the next half-hour after the time fixed for the adjourned meeting, the persons present personally or by duly appointed proxy and entitled to vote constitute a quorum for considering that motion or business.
