This may be somewhat simplistic, but if Qantas wish to remain as the Australian Flag carrier, then employ, administer and maintain in Australia!
I remember it wasnt too many years ago that Asian Airlines used to come to Sydney for their Maintenance, but years of greed (shareholders and possibly staff as well) have eroded what was once the world leader.
We now have a Leprechaun determined to find the pot of gold in another country... and I say to him, your welcome, off you go, just leave our once great airline here and alone... maybe we can find someone who wants to keep Australian Icons IN Australia, rather than sell off our heritage as successive previous Governments (both varieties) have been quite happy to have happen.
