At the time of the CWS closure there was significant discussion about the need to have navaids in the Melbourne basin for training & currency, which has pretty much been ignored by AsA.
There was also a significant discrepancy between AsA policy and statements made by the AsA rep to the RAPAC meetings at the time of the CWS procedure deletion. RAPAC was told that a training procedure was on the worklist, but it never was.
The decision to not repair YWE after damage by vandals was made unilaterally by AsA. If you trace the RAPAC minutes at that time it was an open agenda item for a year or more before AsA declaring that sending a repair crew to a National park within 1 hours drive of Melbourne was an unacceptable OH&S risk.
