While this has probably been dealt with and good advice given, it is best (in my opinion) to try to be ahead on the game where EC members are trying to not get Motions up at General Meetings, and so you proposing a motion to the Secretary of the EC well in advance of the AGM would be prudent.
Refer below: (Schedule 2 Extract)
36 Requisition for motion to be included on agenda for general meeting
(1) Any person entitled to vote at a general meeting of an owners corporation on a motion that does not require a unanimous resolution may, by notice in writing served on the secretary of the executive committee, require inclusion in the agenda of the next general meeting of the owners corporation of a motion set out in the notice and the secretary must comply with the notice.
(2) The secretary must give effect to the requirement of the notice.
(3) Subclause (1) does not require the inclusion of a motion on the agenda of a general meeting for which notices have already been given in accordance with this Schedule but in that case the motion must be included in the agenda of the next general meeting after that.
(4) For the purposes of subclause (1), an owner of a lot who, but for the fact that the lot is subject to a mortgage or covenant charge, would be entitled to vote at a general meeting of the owners corporation is entitled to vote at that meeting.
It would be appropriate to copy the Strata Manager to make sure they get it on the agenda, if they are responsible for preparing the agenda. The fact that in Schedule 2 36(1) states that the secretary MUST comply is important.
Hope this is also of value.
