Out of the three RAAF joint user bases (DN, TL and WLM) WLM is the only one still classified as a MIL airfield. Your compaints about being held may be valid at DN or TL, but the aggrement to set up Newcastle Airport at WLM is so strict and conditional you don't have a right to complain. Afterall, even RPT jets get held at WLM to make way for MIL jets.
On your other point, ATC don't gamble when they separate aircraft. Odds don't come into play. Safety always comes before expedition, they don't come hand in hand. If something has the potential of causing an accident, it should be done another way. You don't have the authority to bet peoples lives on your so called odds.
