" what does puzzle me is why the airline concerned chose to potentially upset the Australian regulatory agencies, the same agencies who could presumably hold the aircraft as evidence for a long time, the same agencies who ultimately determine the right of Emirates to fly to Oz, etc."
You are extreamely 
wrong to think that the ATSB is not aware about the action plan !! otherwise, since the incident ,a dozen of flights touched down and departed from YMML,YPPH,YSSY,YBBN...where were the ATSB ??? probably waiting for you to wake them up 
Not surprisingly, that does puzzle me (as does the lack of media attention)
Now, you are absoluately naive in seeking media's help
