As a Brit I was pretty shocked to arrive in Australia and see that binge drinking there is next level. The Melbourne Cup horse races is like a national drinking day, my employer took everyone out to get wasted (this was in Sydney, didn't even watch the races) and then it was understood that you'd probably take the next day off.
How odd, I used to work with an Aussie (Sydney) expat and he was glowingly boasting how much better they are at anything because competition. It’s so much part of their culture he said, that they will out-do anyone, even at their core traits (and so concluded that Sydney pizza is better than anything I’ve ever eaten. Me. Italian from Rome :D)
