No, it’s not too much to ask but you must follow due-process and seek the active support of a sufficient number of like-minded Owners to bring about the changes that you seek.
As examples, if the appointment of the new strata management company is resolved at the EGM, then your Owners Corporation will likely need to give a minimum 3 months written notice of its intention to terminate that company’s Agreement and to appoint another; check the termination clause in the document.
Additionally, as there’s currently no EGM Agenda item (Motion) to convene yet another General Meeting to vote on the special levy, contrary to Fair Trading’s advice those present cannot resolve that way at the Meeting. That’s where the active support of other Owners is critical, as a requisition to the Secretary by ≥25% of those (by unit entitlement) is required to force the convening of that further EGM or indeed any other that may be necessary.
