I think you will find QE are more than happy with the services of the three main 147 training organisations in Australia. Considering one of the BNE based companies provided all the B1/B2 differences training for most A380 LAMEs and the other has provided various type courses for QF and it's customers over the years, in fact, their 738 course doesn't even require differences training in order to get a QE company approval. I would question the quality of the services coming from the Nowra based company QE is using for some training though. The mind boggles how so many AF/Eng LAMEs can go down there to play with an antique war bird for a week and come back with no category restrictions on their B1?
