i offen see posts about holding back announcements to ASX. it is illegal- research penalities for infringements


"Under Listing Rule 3.1, market sensitive information must be disclosed to ASX immediately upon the entity
becoming aware of the information, unless it falls within the carve-outs from disclosure in Listing Rule 3.1A (see
below).
The word “immediately” does not mean “instantaneously”, but rather “promptly and without delay”.
Doing something “promptly and without delay” means doing it as quickly as it can be done in the circumstances
(acting promptly) and not deferring, postponing or putting it off to a later time (acting without delay)."

in formulating that announcement if it can't de done prompty- a trading pause or halt occcurs.
