I have just got off the phone from the lady who gave the brief, and she did confirm that the only legal provider of the MET info for flight planning purposes, and therefore the AIP requirements, is Air Services Australia, as they are the ICAO approved standard......
It has 'always' been that way, and this was just a 'clarification' of that....
She did confirm, that in the event of the on line NAIPS not being avbl, then phone / fax / dectalk services are still avbl.
So, even though the original info may come from the BOM, it is up to AirServices to ensure that it is in the 'correct format' for dissemination to the 'Aviation Users', is the message....
Cheers
