In my career in oil and gas I have had dealings with Australians and have been able to observe their culture.
They are just a little bit too relaxed for me, and I say that as a person who has laziness as a pivotal part of his mission statement.
It’s an odd quirk of the masses there - apathy/no worries mate/easygoingness as a pivotal part of their culture.
They love to ridicule the U.S.A. But if the U.S.A. were no longer there to protect them, they would be sitting ducks.
