To be honest, I hadn't checked that section of the website. I've been using the asx announcements page as I can still look up historical announcements - https://www.asx.com.au/markets/trade-our-cash-market/todays-announcements. Select 'Search for past announcements' at the top right. It will say that IHL is no longer listed but there is a link below the list of previous names
Hope this helps
