My strata manager mates will hate me for saying this but the SM is just a delegated functionary of the owners corp, in this regard. To put this simply, you are the boss of the SM, not the other way round.
At any point, the owners corp, as embodied but the strata committee, can resume control of things like the minutes.
So rewrite the minutes to properly reflect the decisions of the meeting (you don’t need to wait for the next AGM), send them to the strata manager and politely ask them to send out a) an apology for sending out inaccurate minutes and b) the corrected minutes as agreed by you and the secretary.
If the strata manager refuses or doesn’t comply within, say, five working days, send the minutes out yourself and, at the same time, raise a complaint with Fair Trading (who will do absolutely nothing – but at least it will be on record that the SM allegedly behaved unprofessionally).
