I'd suggest writing to the ASX Compliance Team (who deal with Listing Rules compliance) and ask them why they didn't feel the need to ask questions about yesterday's trading given a lot of their price queries are based on significant SP movements on higher than average volume.

How they answer your complaint doesn't really matter - but if HIL entered external administration in the short term it would make for very interesting correspondence to ASIC concerning the extent to which the ASX is fulfilling its Listing Rule compliance procedures.
