Well, RAAF Base Edinburgh is an Australian air base, not an American one, hence the designation "RAAF Base" (Royal Australian Air Force). Indeed,
joint operations conducted there in the past have been between the Australian and British governments, rather than Australian and American
governments, although I am sure such liaisons do take place today.
Here is the official site for the base, which is nowhere near as
secretive as Area 51.
The reason why RAAF Base Edinburgh is often cited as a location where classified or experimental technology is tested is due to its proximity and
association with the
Woomera Aerospace Facility, which was a joint Australian-British
facility for weapons and aerospace testing. Until 1999, the site also played an important role in satellite tracking and communications interception,
until these functions were transferred to the infamous
Pine Gap base, which
is a joint
US-Australian base.
Nowadays, however, Woomera is mainly used for the testing of scientific rockets (a scramjet was successfully tested there by a university team, so
it’s not as though it’s a highly classified, I’d-tell-you-but-I’d-have-to-kill-you location) and RAAF Base Edinburgh is a station for the
deployment of long-range Maritime Patrol aircraft and P3C Orions, which patrol and defend Australia’s southern border.
Sorry brodband, but it looks as though Edinburgh is not quite as interesting as your friend’s brother made it out to be.
Edited to acknowledge that Nventual actually posted the link to the Base's home page before I did (sorry mate, wasn't trying to steal your
thunder, didn't see it there) and to posit that the UFOs seen around the area are probably misidentified conventional or experimental craft or
rockets being tested.
