Didn't Qantas and / or Ansett do those sort of flights years ago - "Mystery Flights"?Or were they a different thing?

I'd be there with bells on for a vaccine. Not just for travel reasons. I think the vaccine will also be a requirement to have things like festivals, sporting events and Trade Shows back on line.

Having the medical profession run Government policy is a worry for sure. I'm in the music / touring business and believe me, I want all borders open ASAP. 

Sad as it is, I doubt we'll see any significant inbound or outbound travel here until a vaccine is produced and implemented worldwide.

At least it's some sort of start.
