Sensible analysis
The only sensible pull together of the facts I've read so far was an item on Plane Talking which makes you wonder why the media falls for the naval base theory.
Then I nearly wet myself when someone on a spotter forum pointed out that Boeing operates the communications contract at the base, which reverted to being an Australian naval facility some years back after the US found better ways of communicating with ships and subs.
My step son who works for Virgin Blue said there were lots of A330s, 777s, some 717s and other assorted jets plus at least two Singapore A380s flying as close or not closer than the 630 kilometres that were between the Qantas jet and the base in the 24 hours during which the ADIRU No 1 in this Airbus went AWOL. He also said the quality of work done on the Qantas A330s is supposed to have been really **** house in general and that the rumors are that big red is pretty pissed off.
