The only difference between Qantas and ‘everyone else’ is the size of Qantas domestic network compared to international. So whilst I can see international being paired back quite strongly for the next 12-18 months, I’d be surprised if there was much of an impact on mainline SH crew apart from staying on MGH for the foreseeable future once they get back to about 75% of pre COVID levels. Of course that 75% mark may not be until close to December, or as wheels down Correctly put it, much later if Victoria stuffs up this community transmission.
What to do about international the in the interim? Who freaking knows!
A lot of this comes down to a vaccine. If one of those gets up and going within the next 6-12 months the 12-18 months after that could be flat out.
