assimilation
Those days are gone.
Once, someone who emigrated from, say, Poland, needed a short wave radio to hear their own language, couldn't get kielbasa for love nor money and needed to save half a year's wages to visit home.
Now, people have all the TV channels they had at home, the entire internet at their fingertips and of course Ryanair Stansted-Modlin is often cheaper and always quicker than PKP Warsaw-Szczecin (and that includes airport travel/waiting).
And if ever the concept of Australia is introduced to the new arrivals, it's in the sociological concept of Australia being a colonial, genocidal, racist entity. Rather than a multicultural country we should all be proud of.
Something to blame Yank academics seeking to impose their views on others and r*SSian and Chinese propagandists seeking to undermine the free world are very much to blame for.
