If your registered address as a shareholder is outside...

If your registered address as a shareholder is outside Australia, you are an "Ineligible Shareholder". You TAW shares will not transition into the new A40 ticker. You have, I understand, two options now:
1. Sell your shares (before the end of day of Dec 4, if I am not mistaken). You could then hold your cash and wait, possibly to buy into A40 after the merger. Of course, your future re-entry cost may turn out to be lower OR higher than your pre-merger sale.
OR
2. Do nothing. In this case, after the merger, your equivalent AMAL shares will be sold on the market by a (un-named) Sale Agent (=broker) designated by TAW/AMAL.The designated broker will sell your shares on behalf of Ineligible Shareholders during a certain period -- I have no idea how long; weeks? months? You have no influence upon the price achieved by that broker, or on what date the broker sells your shares. Also, there seems to be no way to monitor whether the Designated Broker's reported sale price matches the actually achieved sale price.
In other words, Ineligible Shareholders are in a weak position; their fortunes could turn out either way.
This is my interpretation after perusing the TAW announcements. Do not trust my words. Read the TAW announcements, especially page 51 of the Supplementary Scheme Booklet (Nov 8):
