The numbers (excl LWOP) are not too far from being right. Yes there are some categories assigning leave, but there are also categories where there is a definite under resourcing.
When/if expansion hulls come to mainline, the 'suck' from training will be immense (there are so many more usable crew when the music stops) and QF will be short of crew. With new jets potentially arriving from mid 2017, people will start to move off existing types very late in 2016, which means recruitment probably need to start vetting people early next year.
