Duds,
I’m not sure from your question whether you’ve received the Notice of AGM or not.
If you haven’t, what Whale says is correct, you can write your own motions and send them to the secretary or SM to have included on the agenda.
If you have already received the Notice, that it’s too late for that.
You will have to content yourself with asking pertinent (or impertinent) questions on the financial reports at the AGM prior to the vote.
Financial Reports should include: Balance Sheet, Income & Expenditure, Non-Levy Income, Levy Position Report and (hopefully) Detailed Expenses (full transaction list).
Go through them thoroughly and ask questions about anything you don’t understand. You’re entitled to.
If one or more interested owners has done that, there’s probably no need for an auditor, unless you don’t get satisfactory answers. Auditors cost money, they usually only check a “sample” of transactions, and it’s not their job to check whether you got “value for money”.
