Two quick things here.
1. Beware Crewing Companies telling you that Airlines are recruiting. They aren't but they are happy to have you on their books. A lot of Airlines that were using crewing companies will not be in the future I expect.
2. I think QF will be dealing with the extra crew they have in house for years before they look outside for any including Ex VA crew. Every Airline is saying years before things get back to where they were in 2019 so a lot of us will be retired and working on our Golf swings by then.
