CAAP 89O-1 talks about the Aerodrome Reporting Officer being responsible for raising NOTAMS for a list of specific items including a catch-all, but they all relate to Safety. I cannot see how commercial considerations can be used to raise a NOTAM. I reckon the Australian NOTAM Office should be challenged on this basis. I'd also suggest the local council should be approached by those affected on the basis of restraint of trade.
There'd be many former operators and users of YGLB turning in their graves knowing what's going on there!
