By "experienced" I assume you mean mainly ex RAAF ?
From my own experience, a few years ago most non seconded Instructors at the school were on payband ASA 7, and earning substantially less than these new recruits - low $90k's.
Maybe they still are ?
Or maybe not; as according to some of the online recruitment opportunities ASA 7 payband now appears to top out at about $130K - not bad if you can negotiate this on appointment ( it was about $100k in my day).
