One thing that I can almost definitely confirm is that Oprah (and the other hundreds of lucky Americans traveling with her) is visiting every Australian state and territory. She'll be packing a lot into her trip! I'm thrilled that she's coming to South Australia, though. I really didn't think that she was coming. People bypass Adelaide a lot.
I have a book of Aussie slang in my apartment, but I'll avoid it and use what I know. I'll add more "culture clashes" as time goes on. This is a lot of fun to do! Some of these things are obvious, but there might be some words that you have never heard before.
Australian word-American word
Car park- Parking lot
Christmas show- Annual work Christmas party
"May I please go to the toilet?"- "May I please go to the bathroom?"
Dunny- Another word for "toilet", although it's not common. Al says it, but people laugh at me when I say it. I think it might be a "country" thing
Doona- Comforter (heavy blanket)
Thongs- Flip flops
I'll add more vocab and slang every once in a while. I hope you're taking this all very seriously!
