So the graph you posted says 20-25% of Aussies were planning (not just wanting) to take a domestic flight within 3 months of restrictions lifting.
Yeah.
But that was 3 months after a minimal 1st wave that was quickly contained as it mostly involved returned travellers. I suspect this outbreak will be harder to get under control and will do more damage.
Then add the loss of disposable income when jobs don’t come back, when job keeper gets pulled, and when mortgage holidays come to an end.
This is not a short term blip in a graph. This is deeply entrenched structural change.
