No.
You seem to have a vivid imagination and not a lot of real world interaction with others.
People tend to largely clump when they collaborate; if you pivot via citeseer on each author in the given paper you'll see a number of different papers in common with each other (and a number of outgroup papers).
Mike Dentith, with an office some ~ 20km away from Curtin, is part of another large clump of papers in the same field - there are some interactions, of course, but the helicopter view of these papers and their co-author networks is not dissimilar to social media interactions that densely cluster with sparser interlinks.
Have you ever generated network visualisations of research papers | social media interactions?
It's an interesting exercise.
That's totally uncalled for and very immature. What's the point? Does it make you feel good about yourself to belittle others? If your assessment of me shows anything about the rest of your qualities in life, then boy, I don't know...
Are you saying that all of these universities act as one on this subject matter to the point that if any member disagrees "it'd be a real shame if something were to happen to them" type of situation? I'm not in geophysics, not local, nor have casual Australian speech patterns, and I have no earthly clue what/who Mike Dentith is or the relevance.
What's the advantage of being mafia-like in the realm of geophysics? If they are actively promoting bad theories from within the confines of Australia, the world is a big place full of other scientists that can dispute outside the control of this purported mafia.
