Just like current statements that it is important to contain costs due to the significant investment required to reduce the average fleet age of Qantas aeroplanes.
Start by going to James Strong's house (and all of his cronies during his tenure) and getting back the bonuses they made by not investing in the business. Strong's tenure was one of sell everything, buy nothing, bank the bonus. Now the company seem to think that current employees should pay for the "management oversights" at the time.
Unfortunately for Qantas Management, most employees have seen all this before, so to say to them that they have to show restraint whilst "management" give themselves massive increases in remuneration (even lower level execs got between 4%-7% payrises), and the board 66%, takes a better sell than they are currently/(capable of) doing.
