Just to add to what Direct.no.speed wrote, ask how many of the latest recruits (excluding the 1 or 2 from OS) came from the RAAF.
And then ask the RAAFies about their manning problems. It's just robbing Peter to pay Paul, somewhere services will deteriorate due to lack of staffing.
At purely military bases the reduced service will largely be felt by military only, but at the joint user bases (Darwin, Townsville and occasionally Williamtown, depending on who you ask) military controllers handle all civilian traffic for the area as well (which in DN's and TL's case far outweighs the military traffic - around 90% civil).
And don't buy the company line of "xx number of recruits to replace xx number of retirements/resignations" - not all recruits will pass the course and of those that do, some will still fail to get rated. We should be training 10% more than we need to allow for this.
