Interestingly, another PPRuNe forum quotes the installed price of a new NDB beacon as between about GBP 30,000 & GBP 40,000 depending on the if power is already available to the site. The equipment component is about GBP 10,000. Thats about $42,000 - $70,000 Aussie installed with antennae towers, the lot! Another commercial company I found in the UK (NATS) conducts annual NDB monitoring that is compliant to the UK CAA requirements for GBP500 or $800 Aussie.
So why not organise yourself along with some other flying organisations and/or clubs and put an NDB in somewhere?
Wonder what it is costing to rename all these places they are ripping ground based aids out of...reprinting charts and all the other doc's that go with it. Sydney is now TESAT
The charts and other documents were a routine release that happens every mid year, so no additional printing cost was involved.
TESAT has been in for some years. At the time the SY VOR was decommissioned the new ID chosen by Airservices at the same coordinates was going to be "SYVOR" for simplicity.
However CASA objected to that, requiring an unrelated waypoint name to be used, hence TESAT.
Don't blame Airservices for everything. CASA has had their sticky fingers over everything. Their Office of Airspace Regulation assesses changes and approves by legislative instruments all air routes and various airspace types each chart and document release.
