One week does not sound like sufficient notice for the AGM. In the ACT, where I am and I am more familiar with the legislation, at least 2 weeks notice is generally required. This does not mean that meeting papers can be put in the mail 14 days before the meeting date. The committee must also allow sufficient time for postage to be deemed to have arrived. From memory I think this 5 working days. In effect the papers need to be mailed out at least 3 weeks ahead. When I was a committee member, we generally did 4 weeks just to be safe.
