There’s a trickle of Greeks coming into Australia, mostly based on preexisting family connections (or returnees whose children have ended up going back). The cafés of Oakleigh, Victoria (the current Greektown of Melbourne) are awash with waiters speaking contemporary Greek slang, rather than codeswitching from 1950s village patois.
But Australia is, as my grandmother once said, πολλά αλάργο,* and most Greeks have indeed fled to Western Europe.
* Cretan dialect for “very far”. αλάργο is Italian a largo.
