This is the list of people's cultural background I know just from Adelaide:
Aborigines, Australian, Kiwis, American, Canadian, Sudanese, Nigerian, Dutch, English, Scottish, Irish, German, French, Spanish, Portuguese, Italian, Serbian, Chinese, Vietnamese, Cambodian, Greek, Indian, Pakistani, Croatian, Romanian, Nepalese, Iraqi, Iranian, Korean, Afghan, Russian, Venezuelan, Brazilian, Turkish, South African, Kuwaiti, Tongan, Malaysian, Indonesian, Lebanese, Thai, Ukrainian, Yugoslav, Sri Lankan, Lao, Mongolian
Adelaide is a good place to live. Very diverse, but racism is very real.
