At the root of most racialism and discrimination is a lethal mixture of ignorance, old fashioned tribalism, fear and insecurity. I first saw examples of it when I was a kid growing up in inner Sydney in the late 40's and 50's. My parents and our neighbors were forever whinging about the Italians and Greeks moving into our street and buying up our houses and 'not speaking English' (even though a lot of them spoke better English than them). I can't remember the issue of 'our culture' and 'way of life' being raised, but it probably came up in some form or other. Later came the South Vietnamese refugees escaping the mess in Vietnam after the US handed it over to the Communist North. Again the same rhetoric about our 'unique' culture and values etc., supposedly inherited from the 'Motherland' far away. I guess the original Australians thought the same thing when the British 'Boat People' started turning up without papers at Botany Bay and Sydney Cove- there goes the neighborhood! (and almost the entire original inhabitants of Tasmania in one of the world's worst cases of genocide).
These days I struggle to see what 'unique way of life' or 'culture' we had was lost because of the arrival of people from somewhere else, unless it was the inequality and discrimination that I clearly remember in the 50's -women denied employment for any reason you could think of, religious discrimination at work ( bad luck if you were a Catholic and the boss was a Mason). Six o'clock closing! I am sure many people of my vintage remember being sent by their mother to the pub, dodging the brawling drunks on the footpath, to collect their father at dinner time as he tried to stuff one more schooner in before last drinks, before coming home for a drunken argument over a dinner of over cooked mutton and soggy vegetables washed down with a couple of bottles of warm D.A.
I was lucky, my old man was a gentle man at heart and never laid a hand on my mother despite the demons that haunted him from his war service. Some of my mates were not so lucky. No use calling the cops, it was a 'Domestic Matter'- part of our 'unique values'. Restaurants? Forget it. Maybe a few decent ones in the flash suburbs or King's Cross. The rest served food that you would not give a dog these days.
Thankfully, the Italians, Greeks and Asians took this bit of 'unique' culture from us and opened up their own restaurants so that now Australian cuisine is world renowned for its fusion of different flavors from all over the world with local food and flavors (including Aboriginal).
And so, the dream of a little piece of Britain in the South Pacific has faded over the years. Bring on the Republic and finish the job!
