I agree with Jimmy on his proposal. Another way is to have a motion on the next general meeting that the owner force, being “That the Owners Corporation resolves to have future general meeting by electronic form only”
You would need to have the strata manager confirm the wording of the exact motion as you may want to meet for the Annual General Meeting as you need to elect a committee.
Then you have that motion on every general meeting so that no one needs to waste time meeting just email back a form with your vote.
You could also at a general meeting have a motion to call the next general meeting, say in 3 months (you set the date at the meeting, again your manager) with owners to provide motions for that meeting 31 days before the meeting date.
That way you limit the number of meetings to 4 a year, they are electronic and you can’t be seen as not allowing the owner to put motions forward.
The owner just wants to whinge and make sure everyone knows how important they are, just like a child.
So give them a voice, but you control when and how.
