The blame sits squarely at the government for privatising the airport and allowing Pearce to exist this side of Learmonth
2FTS et al should be repositioned to RAAF Learmonth. There is no strategic imperative for a training unit to be located in Perth... and... they should be training where they will be fighting.
RAAF Pearce should become a Joint-User airfield with a caretaker unit on the RAAF side and a full civilian airport built on the other side of the runways. Rename it and use it as a civilian airport until the next war. By which time WAC... might... have completed the parallel runway and terminal extensions at Perth.
