I’m in a similar predicament.
Upcoming AGM with a dodgy motion.
Preliminary email to SM returned the reply that the motion was in order, which didn’t actually answer the objection I made.
Next will be a more detailed email with reasons why the motion is defective. Which I am sure will get the same reply.
This is an experienced SM who is just trying to gaslight me and others.
Like you my arguments will be well supported by reference to the act.
if the motion is not withdrawn at the agm I intend to get mediation and then go to NCAT.
