It’s a RAAF base mate, they can do what they damn please with it, not your call mate. (I'm not ex-RAAF, current RAAF or any of the other services). I also believe it's a fair trade for the 'taxpayer' to fund their flight training.]
Tell that to the Defence Minister and the Treasurer. Point Cook is desirable residential land. The locals have been complaining about its use as an airport for at least fifteen years. The road access to the whole area is choked and problematic, so is public transport. It has a stack of infrastructure - barracks , mess, etc., but I wouldn’t know if any of it is in an acceptable state these days.
