National Best Bid/Offer Crossings are displayed to all ASX Trade users in the Trade History window with a condition code of NXXT.

New and Fill order records are displayed in the Order History window with condition code NX and may be viewed by all users of your Trading Participant. National Best Bid/Offer Crossings do not update official prices such as open, high, low, last or closing prices, however, they do update the daily trade statistics of volume and value only.

I hope this helps
