The RAAF have been very precious about their airspace for a long time.
With good reason bob as it keeps getting chipped away at. eg civvy airliners flying through willy restricted airspace...it was sold as.... wont effect training ops in the airspace yet we have been made to restrict operations not above 15000 many times due over flying traffic.
Civvies whining about not being able to use mil airspace is ridiculous. Look at all the G class airspace out there that can be used by all and sundry, just because people want to do a scenic trip with there wife and toddlers on board dosent mean mil ATC should change procedures.
