AGM 2022, page-13

Andy, if Biddle does show up he will acting as Chair until the end of the meeting and thus he will be voting with the Proxy votes given to the Chair: The Chairperson of the Meeting intends to abstain from voting undirected proxies in relation to Resolution 2.
Just be mindful of this: In exceptional circumstances, the Chairperson of the Meeting may change their voting intention on any Resolution, in which case an ASX announcement will be made.
Also please note: Shareholders who are not attending the Meeting physically will be able to listen to a live webcast of the Meeting. The details of this audio webcast will be provided to Shareholders by way of an ASX announcement at least one week prior to the Meeting.Please note that the webcast is provided for convenience only. The Meeting is not intended to be, and will not be, held using virtual technology. As such, while the webcast will allow you to listen the Meeting in real time, it does not facilitate participation in, or voting at, the Meeting.
So Biddle will have to be there in person and no Zoom appearance because if he does that trick I'd be onto ASIC long before the meeting ends because what ever privilege given to any Board Member and not afforded to Shareholders will open the meeting to possible challenges and the voting to be declared null and void, also it against the rules.
