ASIC v ISX Hearing, page-712

The only way to be sure to know what is happening is to turn up - which you could do, but for a mention, it's unlikely that there will be any outcome published by the court, other than if ASIC provide an update as mentioned by @jlo2012.

I haven't been keeping up with this case, but from memory (and from reading between the lines of the ASIC release at https://asic.gov.au/about-asic/news-centre/find-a-media-release/2022-releases/22-240mr-grant-thornton-and-auditor-charged-over-2018-audit-of-isignthis/), the accused has plead not guilty when they appeared on the 1st of September (which would have been the (first) mention hearing), so I'm guessing this is a contest mention.

This page provides a good overview of the process (albeit from a victim of crime point of view): https://www.victimsofcrime.vic.gov.au/going-to-court/types-of-courts/court-process-in-the-magistrates-court
