IMO the big advantage to Australia of the post WW11 immigration, British, European, Italian, Greeks and Jewish immigrants was that they assimilated and became part of the mainstream community.
Many came to work on the Snowy River Scheme which would not have been achieved without the immigrants.
No government handouts in those days. Many famiilies living at Villawood Immigration Centre until they got on their feet, which they did. Many didn't speak English but worked hard to learn.
We needed them and they needed a new beginning. These people helped make Australia what it is today......heaven on a stick.
Assimilation is the key word.
