Australians think that because something is "Australian" is automatically better than anything else in the world.
For 50 years we have been believing in our own bull****, this came about from the Bradman era a,d progressed through the 50's, Australia dominated world sport, not because we were intrinsically better, it was just a matter of dumb geographic luck that we were in a part of the world where we always had good weather and the athletes could train more effectively, and partly that Europe was recovering from WW2.
Once the rest of the world got rich enough to build indoor training facilities, and playing arenas, we were no longer the top dog.
Unfortunately, the Australian psyche & business psyche has never left the 50's, we still think we are better han everyone. The truth is very different.
