This was not directed at Australians at all.
It is easy to see how an Australian might assume that.
It is about survival methods and technology.
It just happens to be, by coincidence, that the Ark mentioned in this thread happens to be planned for Australia - the same location as one of the oldest known still surviving human groups. Maybe only a Handful still have knowledge of the ancients - maybe none are now left to learn from.
Again, coincidence.... nothing more.
