Ann: Share Consolidation update & despatch of holding statements, page-9

Ahh, I get what you're asking. Technically you should be able to, but unfortunately Superhero is not CHESS (Clearing house electronic sub-register system) sponsored.

More info available here - https://passiveinvestingaustralia.com/superhero-review/#is-superhero-chess-sponsored

"This means with Superhero, your shares are not held under your own HIN in your own name, and you are not the legal owner. Australian shares are held in custody on your behalf by a third-party company — a custodian — Superhero Nominees Pty Ltd, which has a single institutional HIN, and you are the beneficial owner."

So if Superhero won't let you trade your beneficial shares under the MDCDA code, not really much you can do. It's rarely an issue, but it's a reason I'm personally not a big fan of trading platforms like Superhero, or instruments like ADRs for that matter.

Good news is you should be able to trade as normal when your shares revert to MDC common on Thursday.

Hope that helps
