Compared to the cost of operating a Chinook / FA18 / Seahawk salary is chump change.
There is also the fact that those Officers who are undertaking other positions are actually required. If you move to a flying rank structure full of WO's either the WO's are going to have to take on those roles OR your officers are going to get pretty hacked off with having to much time behind a desk and not enough time flying.
There is no getting fired if you spend too long in a given rank. Up until recently you could opt out of getting reviewed by the promotion boards. The system you describe does happen in the US but not in Aus.
Additionally the RAAF (Not sure about RAN/ARMY) have specialist aircrew positions where that person will remain in a flying position at a stable location and opt out of some other things (such as promotion, pay increase etc)...
So essentially WO aircrew not required.
