I would recommend economist, George Megalogenis's excellent book, Australia's Second Chance, about how crucial migrants have been to our economic success.
He writes, "Australians have proven remarkably adept at absorbing new arrivals without losing the national value of fairness. No migrant group has ever formed a permanent economic underclass in Australia."
We are proud of the fact that outside of Israel we have the largest number of Holocaust survivors in the world - here you can be safe, here you can build a new home. Each wave of immigrants has added immensely to Australia's cultural and economic life.
I hope we can remain a free open trading nation and 'innovative nation.'
As our Prime Minister recently said,
"There's never been a more exciting time to be an Australian."
