Australians
Every time an American production portrays Australians on screen they just insult us. Never has an American come close to our accent! And we have as many variations as you lot!
For the love of (your) god, only hire Australians to play Australians otherwise we are only a nation of jokes to you people!
Not to mention the scene on Sydney Harbour set in 1974 with buildings constructed 30 years later in the background; but who cares right? It's only Australia.
