It is possibly a bit of a grey area, but operations like this have been going on for years.
I can quite easily call myself Howard Hughes Aviation, set up under a tree, sell individual seats, at set times, to any destination, then contract another company (can even be a charter AOC) to operate the service for me! None of this contravenes any legislation, aviation or otherwise! Perhaps the one valid point that you do have, is with regard to scales and weighing of pax, but that is a matter for the AOC holder and/or CASA, not the boooking agent!
Can't really comment on the low hour pilot as I don't have all the information, but it could be just people with an axe to grind!
As for the CP not going near the place for months, do you understand the CP's obligations? Is he required to visit?
Cheers, HH.
