Ann: Pause in Trading, page-33

They don't say it is because of an aware letter. From an actual aware letter that ICI received in 2024:


Trading halt

If you are unable to respond to this letter by the time specified above, or if the answer to question 1 is “yes”
and an announcement cannot be made immediately, you should discuss with us whether it is appropriate to
request a trading halt in ICI’s securities under Listing Rule 17.1. If you wish a trading halt, you must tell us:
• the reasons for the trading halt;
• how long you want the trading halt to last;
• the event you expect to happen that will end the trading halt;
• that you are not aware of any reason why the trading halt should not be granted; and
• any other information necessary to inform the market about the trading halt, or that we ask for.
We require the request for a trading halt to be in writing. The trading halt cannot extend past the
commencement of normal trading on the second day after the day on which it is granted. You can find further
information about trading halts in Guidance Note 16 Trading Halts & Voluntary Suspensions.

You must be new to specs if you aren't aware of the above as it is standard in EVERY such request the ASX makes.
