I don't know if this will help much Fed Sec, but if could be useful. I've been told that Air Vanuatu who used to have their 737 Maintenance done by Qantas in Brisbane has now been told this will no longer be available. Surely if the Engineers were getting all their work done for Qantas and this was being done as well then they are deliberately losing money that would have been given to them for this work for no particular reason?
There may be evidence of other such "Minor" work that brought in extra money being allowed to disappear to the deliberate detriment of the Qantas Group.
