Just out of curiosity: Does NSW have the option to lodge an ‘Absentee vote’ rather than appoint a proxy?
Here in the ACT an owner can do either. Meeting papers must include a form(s) (which is approved by the EC) to enable both forms of voting.
A proxy can be appointed to vote as directed for some or all motions or as they see fit and can vote on the owner’s behalf on any procedural motion or motion to amend a motion that might come up.
On the other hand, an absentee vote can be submitted for each motion that is listed on the agenda. Obviously you can’t have an absentee vote on a procedural or amendment motions because you don’t know about them in advance.
