Voting on any issues will not be done during the meeting or after board presentations, but rather online. They will have a cutoff time of 5pm the day before the meeting.
This could also mean that members have to vote before they know about that year's financials, though Roger Clarke, the current IA secretary, denied this would be the case.
A third implication of the change is that no issues can be raised during the AGM and be voted on. Thus if there issues of financial instability, for example, these could not be raised in person.
He said the financials would be made public long before the AGM was held and questions could be asked before the vote closed.
"There's a minimum 21 days from Notice of Meeting to closing-time, and we're aiming to provide Notice somewhat further ahead of the meeting than that," he said.
"The reason for closing voting prior to the meeting is to ensure that the results are available in time to announce them during the meeting. Within-meeting voting by electronic means, inevitably over diverse channels, is a nightmare best avoided."
Asked what would happen if there was a positive vote on an issue and there was no quorum at the subsequent AGM, Clarke said: "All business would remain in limbo until a meeting is held at which a quorum is
present. Then all business would be transacted, including the announcement of the results of the votes.
"The Corporations Act and the law of meetings can be pretty hard reading at times, but the processes are fairly effective in enabling governance to be sustained but business to be done."
IA vice-chair Keith Besgrove told iTWire that arrangements for the voting and its timing would be discussed at a board meeting on 3 September and he expected arrangements for the AGM to be finalised that day.
