"From 1977 through to 1991, Australia resettled around 150 thousand Vietnamese refugees and migrants. As we know the White Australia policy ended 50 years ago this year in 1973 so we could see that the arrival of Vietnamese refugees was really the first test to the disestablishment of the White Australia policy."
Fewer than 700 Australians reported Vietnam as their birth place in the 1971 census - but that number grew to more than 80 thousand 15 years later.
In the latest census, there were more than 268 thousand people who reported Vietnam as their country of birth.
