I don't think anyone is doubting the inexperience levels at RAAF locations. I have read the ATSB report and it is a wee bit biased with criticism aimed squarely at RAAF ATC, there is little mentioned on AsA issues or their LOS incidents (strange given some recent big ones).
At the end of the day inexperience is always going to occur when the average cycle of a military controller sees them move to AsA, or other ANSPs, when they can leave the RAAF at around the 8 year mark. This then sees a need for RAAF to further recruit and this then leads to that inevitable cycle of inexperience. AsA controllers generally stay in location and over time skills developed become rote. I have worked both Military and AsA with enjoyment in both. I just find it hard to fathom a poor one-sided report being released.
