Simon Why would you expect to see anything like that marked on a WAC - which is purely a 1:1,000,000 topographic chart that is overprinted only with aerodromes, isogonals and spot heights in feet. To find information like that you need to use the ERC or TAC (which are IFR navigation and VFR planning charts) or the VNC and VTC which ARE aeronautical navigation charts that include airspace information. Further, CASA is not the airspace administrator in Australia - that role is performed by Airservices, which is set up to make a "dividend" for its sole shareholder and hence to maximise profits within the constraints of its Act of Parliament. Frequency pairing (or more usually multiplexing) has a significant safety cost which for some reason ASA finds tolerable when few if any others do - but few others seem willing to pay to eliminate the safety risks. 122.7 may be dedicate to the gliding fraternity but is not there to allow us to bury our heads in the sand - just to use sensibly without inconveniencing others. All is compromise and we should respect the privilege and use it sensibly.
