Ann: Liquidation and Sale update, page-6

The ASX will delist the company in August, unless the backlog of financial reports is filed in its entirety. (Not going to happen; delisting is a certainty.) At that point, there are companies that will take the shares off your hands in return for you paying them a nominal fee to cover their costs in doing so.

In other words: you don’t need to wait for the company to be wound down; you only need to wait until the delisting. And possibly not even then: if I still held Redflow shares (I don’t), I would have reached out to one of these companies and asked them if they would take the shares, despite their not having reached the point of delisting, so I could crystallise the loss before the end of the financial year.

Here’s a starting point (hopefully it won’t be blocked by Hotcopper; if it is, go to delisted dot com dot au, and go digging.) https://www.delisted.com.au/sell-your-worthless-shares/
