I found out my Computer Share Registry login (haven't used it for years) and my SP1 shares is currently with Computer Share Registry.
it's automatically change my HIN number to SRN number (may be because of the delisting from ASX).

My ISXFEU shares is currently with Automic Share Registry (haven't used it for ages). Not sure why ISX management using different share registry companies.

Anyone know how to sell SP1 and ISXFEU? I don't think SP1 is in Primary Markets. Are my only option is Delisted.com? The fee is quite expensive.
