Aviation in the army plays very much second fiddle to the other corps. It's just a function of where the army has evolved from and what its focus and point of view is. I guess you could say in the Army's eyes, the choppers and RAAF transports are just buses, the RAAF jets are just close air support. Not necessarily right or wrong, just a point of view.
So if you're in the army as a pilot you're not as much of a big deal as you would be if you were an infantry, special forces, or tank officer.
