There have been a lot of South African immigrants to Oz in recent times, so I’m wondering, OP, if any South African words or phrases have started to make their way into the vernacular. Or, indeed, if anyone else has noticed the odd one creeping in. Here in the north east of England, we haven’t seen the influx that has taken place in London or other parts of the UK where new words or phrases might be more noticeable.
Donga is a common enough word in Australia that came from South Africa.
Jaapie is used in Australia to mean “South African person”. I gather this term is used in South Africa to mean an average Joe.
Apart from that I can’t think of any words of South African origin in Australian English that are not part of British and American English, but I will give the matter some thought
