This group covers the airspace surrounding Sydney, Canberra, and Melbourne, as well as the airspace joining these cities. The en route corridors consist of Class A CTA from FL180 to FL600, underlain by Class C CTA from FL125 and Class E CTA from 8500 FT.
Around the capital city airports, Class C CTA exists in cylindrical steps ("upside-down wedding cake") and a Class C CTR exists over the airport. Capital city general aviation airports are overlain by Class D CTR which may vertically adjoin the Class C CTA.
Class C CTA steps underlain by Class D CTA steps are established around Albury. A Class D CTR is present over the airport.
The corridor between Melbourne, Launceston and Hobart consists of Class A CTA between FL180 to FL600 and is underlain by Class E CTA between FL125 to FL180. Over Tasmania, Class C CTA steps down from FL125 in irregular steps and cylindrical steps around Hobart and Launceston. This is underlain by Class D CTA and a Class D CTR exists over each of the airports.
