The Aussies are doing a fantastic job imho but there will be background information that they are unable to share.
I think this is what makes it frustrating.
There is always going to be a hierarchy of information in a situation involving various countries and agencies, as well as various conflicting interests.
So trying to adjust our own mental settings, if you like, to take into account the fact that NOT all the relevant information is available to us, quite deliberately, is really almost certain to lead to degrees of conspiracy theory, because we simply don't know where that line is drawn between clarity and obscurity.
And there HAS to be a line, somewhere.
