Dick,
If you recall, the ILS in Nowra was installed as a civilian project, for expected civilian demand, in part generated by the growing general population of the NSW south coast drawing airline services, and in part by the planned aviation centered industrial park planned to be on the aerodrome boundary.
The navy attitude to the use of their runway resulted in several big multinationals that were going to build largely defense related industry projects at the site pulling the plug, when firmly informed that they could not expect to have regular access by air.
Result, all that remains is an ILS that navy basically can't use, and never needed.
Amazingly, the Liberal then member for the area supported the navy. Another own goal and still some of the highest unemployment rates in NSW, all these years later.
Tootle pip!!
