Two changes currently proposed are:
1) National Standardisation of Class A and E Airspace• Class A airspace will be applied from 24,500ft (FL245) to 60,000ft (FL600).
• In medium and high density airspace, the Class C upper limit will change to FL245 and in low
density, the lower limit will be raised to FL245 (from 18,500ft (FL180)
• Class E will remain as is (in the Mildura, Tasmania and Dubbo corridors).
• In low density continental areas, Class E airspace will be lowered to 12,500ft (FL125) (excluding control areas).
• Class C airspace will be introduced underneath Class A airspace in medium and high density areas where Class A airspace has been raised.
2) Transfer of control responsibility of surveilled Class C airspace from Air Traffic Control Towers at five regional locations to an Enroute sector in either Melbourne or Brisbane Air Traffic Services Centres
