@just get on with it said:
Any proxies given to the strata manager after the scheduled start of the original AGM should be considered invalid as they should be received by the secretary prior to the meeting date/time (and at least 24 hours before for a large strata scheme).
But the proxies aren’t for that meeting they are for the adjourned meeting that will take place in 7 days time, and then the SM can hold the meeting because he has all the proxies from the people at the first meeting.
Seems to me a sensible soloution otherwise everyone has to turn up again for the rescheduled meeting.
If these proxies weren’t allowed just 1 owner could turn up at the adjourned meeting and decide every motion based on his vote which would be totally unfair.
