"In Moorabbin’s case, the Chinese Government owns 10% of the airport as well as three flight training schools at the base."
Scuse me, but did I read somewhere that the Airports Act precluded Foreign entities or Trusts from owning Airports?
Bit strange, MB has Chinese investors, BK is owned by a trust, the head lease holder for KSA resides in the Bahama's.
Leady is right regarding Sydney west. With its CTA zone devised using 1940ies algorithms, IFR arrivals into BK will be almost impossible. The old 18/36 runway, with an upgrade, could have been an alternative, but they closed that, contrary to their lease, to facilitate a development shark building a DFO for aircraft to crash into.
