Below is an extract from the Airservices Regulation 4.12:
"(3) NOTAMS are to include:
(a) aeronautical information required to be published in a NOTAM by:
(i) these Regulations; or
(ii) the Civil Aviation Act 1988 or the Civil Aviation Regulations; or
(iii) any other Commonwealth law; and
(b) other aeronautical information, of importance to safe air navigation, that:
(i) requires early publication and can be published more quickly in NOTAMS than in the AIP; or
(ii) is of temporary relevance."
Part (a) says NOTAMS are to include information required by Reg's, Act or Commonwealth Law and (b) information affecting "safe air navigation". Commercial considerations do not fit into any of the requirements to issue a NOTAM. I would suggest the airport users challenge the NOTAM Office to have this withdrawn.
