At the door the Automic share registry people will probably ask you for your AGM Registration Card.
You need to take both AGM Registration Cards providing your wife's is filled out correctly
So do not leave it at home. It is important to take with you.
They will be able to see how many shares you both have.
If your wife is not going she will have to appoint a proxy on her AGM Registration Card. Vote and sign and date etc. She may appoint you as her proxy providing she is still talking to you after seeing the share price!!!

Have a read of the form. It is all explained on the form.

Any questions ring the share registry in the morning.
Just make sure you have both AGM registration cards with you at the door if you want your votes to count.
Or you want to ask questions as a shareholder
I just voted online yesterday before the 3pm Sydney time cut off as I am not going to the agm.
Hope this helps and I have got it mostly right.
Enjoy your first AGM, looking forward to the feedback from the people who are going.
