Under the Strata Schemes Management Act 1996, Schedule 2, Part 2, Clause 31 (1) (a), an annual general meeting of an owners corporation must be held in each year on a date not earlier than one month before and not later than one month after each anniversary of the first annual general meeting.
So that is very clear, one month either side of the anniversary of the first annual general meeting. Maybe if this were pointed out to the members of the EC, they would act. Not sure what penalty would apply to the members of the EC or to the OC for non-compliance.
