Recommendation 12.
The Civil Aviation Safety Authority delegates responsibility for the day-to-day operational management of airspace to Airservices Australia, including the designation of air routes, short-term designations of temporary Restricted Areas, and temporary changes to the classification of airspace for operational reasons.
Have heard a rumour CASA may not support this recommendation, though why staff in their airspace regulation office in CBR would be involved in the designation of air routes and short term designations of temporary restricted areas I don't know.
Air routes are to assist flight planning and ATC traffic handling, and temporary restricted areas tend to be for such things as police sieges and other short notice emergency situations, which one would think should be handled by ATC as part of their real-time airspace management.
