I suggest you closely read Schedule 2 in particular as it relates to holding Strata Committee Meetings. If you find that the requirements of a strata meeting are not being adhered to by the strata committee and/or the managing agent (if there is one) , I suggest you apply for Mediation by NSW Fair Trading, see
https://www.nsw.gov.au/housing-and-construction/strata/disputes#domediation
If your committee is behaving this badly regularly, then apply for Mediation (with the OC) ASAP.
Do not warn your committee of your action. If you do, they will no doubt ask you to withdraw your application.
Do not wait to apply as it takes some time from you applying to when the Mediation takes place.
