In answer to your question previously, Aussie oil companies only have an obligation to report to the ASX on a weekly basis, while a well is going down.
This is only an obligation, not a rule set in stone and it is also the reason, why operators can dig a well under a "tight hole" regime .... this is where NO news is released, until the operator is ready.
A daily report from the wellsite is required, by the company itself and a copy of the main details go to the mines department and some other petroleum organisations ...
Oilfield etiquette usually allows the Operator of the well or lease to release any public announcements first ... though this does not always happen, as we saw recently, with HDR ...
hope this helps some
