Technically that may be true, but the Feds or CASA can't be expected to turn out to every accident/incident and interview the people involved etc. I know that at Bankstown for example, when the services turn out, the State Police are called directly to turn out and they control the scene etc (once the firies finish doing their thing and so forth) and then interview the pilots etc. I would imagine or more "investigation" was required, then CASA/ATSB would no doubt take over.
I have never seen the Feds at BK before... Investigating an accident I mean.
