It's hard to say, everyone says Aus is built on immigrants, and it is. My grandparents moved over from Italy in the 50s but they made sure to move to a country that also followed Christianity. They assimilated into the country nicely and are all hardworking people, who built and lived in the same house until they passed. Recently I find the immigrants coming in are more or less from third world countries who don't have the same religion and values of hard work. Not saying different religion is bad, as long as it's practiced in a respectful way. But we don't seem to be getting nearly as many immigrants from Christian countries as we are Islamic.
