AsA v RAAF
Ok, poor choice of words.
What I meant was at least in the RAAF you can excercise two very different ratings at essentially the same time, i.e. do some approach then migrate to the tower.
With AsA you generally only do one type or sector, and depending on the staffing situation it can be very difficult to move to another area.
Having worked and trained both RAAF and AsA, I haven't noticed any real differences in quality it comes more down to the individual than the organisation they trained with.
