By the time Qantas has completed its outsourcing, Major international airlines will be bringing their maintenance back in house.
Nothing new there. BA did this many years ago when they established their maintenance hangars in Cardiff as a separate entity, British Airways Engineering. It came back inhouse within a reasonably short period of time.
The unfortunate problem with QANTAS management (and it has been a problem for quite a while now) is that they believe they are smarter than their counterparts and won't make the mistakes they make. None of their counterparts grounded their own airline in spite of their workers or the travelling public.
