Thanks Patrick. According to this https://hotcopper.com.au/threads/ann-dtc-election-process.7624265/page-52?post_id=70772101 , IB will not accept the stock as it’s a micro-cap, unfortunately.

Also, according to this https://www.ibkrguides.com/kb/article-3503.htm?cid=23945609-19e7-4ccf-89db-35f35ce0f7d0 "IBKR Australia does not support individual HIN registration. Instead, IBA Nominees holds all client positions on an omnibus basis with BNP or the applicable sub-custodian. Accordingly, you will not receive CHESS statement and information directly from the registry", however it is not relevant to overseas stock, but might be a limitation (risk) if you want to hold Aussie shares.

I have contacted NAB to get clarity on their DWAC fee.
