Further to the good comments by S, I suggest that in the first instance, you email the Secretary or agent to ask “when is the AGM to be held as I want to submit a couple of motions”. Getting a time frame from the Secretary or agent will help your planning to make any inquiries you want to eg with contractors etc.
You can plan to investigate the matter all you want before any AGM; speak to whoever you want and research the topic thoroughly, so long as you know when the AGM will be held.
You could also ask the Secretary or agent if they are planning any general meetings before the AGM.
If so, when will that take place and you’ll submit the motions to that meeting instead. I mention this because a cunning committee could hold a general meeting sooner than you think to vote on a (possibly expensive and controversial) proposal or a quote. This will disadvantage those owners who thought they had time before the next AGM to investigate all the possible options available to them and to robustly discuss those options amongst themselves and seek clarification in writing from the agent or committee well before the vote.
In my experience, an AGM (in the context of asset renewal) often lists an issue with 2 often expensive quotes using the “Yes Minister” tactic: there’s the quote they want you to pick and another quote that will be described at the AGM as “unreasonable” or “deficient” in one way or another. They’ll make it seem like it’s “courageous” to opt for the “deficient” quote.
Such tactics leave no time to look too deeply at the quote, who it benefits most, the contractor’s track record, the installment calendar (in the case of a special levy) etc.
A cunning committee may spring an AGM on you with little notice and you must avoid being caught out like that. Get on the front foot asap.
Good luck.
