Your missing the point , FIFO numbers stay the same so we can do what we do best - sell rocks to other people
The pax numbers to the point of departure decrease as no more transcon FIFO anymore - so the story is a net loss
Have a look at the adverts on seek for FIFO workers, all contractors now insisting you reside "in-state" (breaching the Constitution , like who cares ? ,
the States/Territories have been doing that from first day of Covid - Feds haven't acted for I would guess a number of reasons)
You have to start seeing what has already & will happen - Covid has made structural changes to "how" people will work & that is going to significantly effect pax numbers
& I'm not aware of the numbers re: $$ for FIFO , I am sure they are significant. But let me ask you this , what do you think the margin would be ? - 20% at maximum ?
