My theory is that Australians have always struggled with multiculturalism.
This is hilarious if it were not so serious!.
Let me however trace (inadequately) my 40+ year experience of living in Australia
We came to live in Australia in 1967. It was MUCH more ethnically diverse than rural NW England.
There had been lots of Italians, Spaniards and Yugoslavs (as they were wrongly termed then....see flags attached of kingdom break up)
In my High School class there were Anglo-Australians, Maltese, French & Spaniards.
In later years I went out with an Italian, my sister with a Croatian, and we ended up marrying into an Italian family; a Polish, Welsh Family; an early Yorkshire and Australian family; we have not yet married into an indigenous family, nor an African family, or an Asian family.
My daughters mock me (surprise surprise) " "Dad wants us to to marry an indigenous or Asian person". I would be more than happy
I suspect that this is the experience of most 'Australian' families.
My dearest (Welsh) friend was married to a Latvian Gentleman. I use the term 'gentle' deliberately. He was highly intelligent. He was gentle and respectful.
Anton, I salute you! As his extraordinary wife died, her faith; his partnership was outstanding.
I have gone on.
