There are 200+ of the most junior crew on long term leave without pay. They will need to be recalled and re-trained before external pilots are hired.
There are the remainder of the B744 pilots who will need to be re-allocated and re-trained.
No A380s are currently flying. All A380 crew are available for movement onto other fleets (if needed).
Many A330 crew are stood down still or on partial pay.
Due to the border closures in WA and QLD the 737 pilot workforce is not being properly utilized. In addition a large amount of that workforces flying has or is going to be outsourced to Alliance and Network in the coming years.
There will not be a need for pilot recruiting in QF for a very very long time. And with commands now running at 18+ years you will be a co-pilot for the majority of your career now.
