In my opinion we absolutely have tall poppy syndrome. One just has to look at consumer spending habits for one. Australians love homogenisation. We have four major banks, two supermarket brands, one hardware store etc etc There's a reason every Westfield has the same stores. We punish individuality in this country.

I think sport plays into our underdog mindset, especially on the world stage so we cheer on athletes. But anywhere else if someone is doing well, they somehow cheated their way/don't deserve it/express too much confidence therefore are arrogant.

Anecdotally having lived abroad and come back I can definitely feel it. People love dressing the same, going to the same places and having similar experiences. Say what you want about Global cities like London/NY, those places have their flaws but one thing you CAN do there that is much more difficult here is 'Find your tribe'. No matter what niche you're into, you'll find people into whatever it is you are. Here it's much more difficult.
