Having 3 people (all Americans, but not "white") get rejected from bars and clubs every single night of the week, people yelling at them walking down the street "go HOME guy! FUCKING GOOK!" etc etc. Happened multiple times a week to at least one of the guys from our group. These guys have been all over the world and never experienced racism at that level, sure from time to time they'd get comments in other cities, but not anything like they did there.
What area of Sydney? Where you hanging out in the ghetto or something? (Not that Sydney has a REAL ghetto)
I mean, I was in the CBD and I saw all kinds of people... never heard anything like that.
