Back in 80/81, according to a guy I shared an engineering course with in Brisbane, Willie was one hectic place when the Mirages were tearing around the place. Owing to their short duration , multiple sorties per day were the go. Granted this was of an evening but the era must be taken in context before bashing the modern system.
When I was in cadets in the 70s and EVERY time we were billeted at RAAF AMB, that place was full on from first light till after dark. Either F111s or Canberras or the milk run C130s...not to mention the Iroquios and Chinooks.
......context! The RAAF was pretty busy back then.
