So we have guesses of 250 over 60,
longhaul 111 over 60,
more than 50 over 60 short haul,
Not forgetting shorthaul can stay on working and some long haul can move seats/aircraft.
So 200 odd leave in the next 3-5 years at best. 10% of the ranks at best over a few years.
Expansion should be over that. Instead things are reducing.
Any way you put it, I do not believe that many are 'close' to leaving anytime soon.
Go back 30-40 years of recruitment and there aren't many retirements in the pipeline.
Stagnation and few retiremnts over the next few years will not see much of a good career prospect unfortunately for QF seniority numbers.
