I’m not sure on this either, sorry
@cwadrian. In your shoes I think I would first contact Computershare directly and ask them how to vote. They are the company’s Registry regardless of the domicile of the individual investor. Their contact page is here:
https://www.computershare.com/au/individuals/i-am-a-shareholder/contact-usScroll to “I am a shareholder” and use their online form option to send an email query. I am sure they will get back to you with advice within 48 hours or do.
Someone else here may have another suggestion based on similar experience, or one of the SAG team might see this, know a better way, and respond. I’m sure there are a few of you who are non-ANZ based and wondering if there is a way to be counted.
