AGM general business

At our recent AGM I was told by the Strata Management (SM), the Owners Corporation (OC) can’t include general business as a item in the agenda. Evidently there are new changes to the Act that preclude general business  as a item for AGMs.

Is this true? 

Also, I was prevented from changing the order of items on the agenda. I wanted to move the item dealing with selection and use of an auditor to later in the meeting after examination of the financial statement. The SM, as Chairperson, prevented this.

Is this correct?
