I believe that we are in danger of being swamped by Asians. Until the 1970s, very few people from the different parts of Asia were allowed into Australia as migrants. Now, there is no official White Australia policy, yet it is not so simple for people of Asian heritage to 'join', that is be considered as belonging to, mainstream Australia. In discussions of citizenship, notions of inclusion and exclusion are generally conceived of in the broad sense of a person being a legal citizen of a country or not. However, such divisions also exist among those who possess formal citizenship status.
Citizenship has different levels.
At the paper work level I know I'm Australian. 5 Mai, also an Australian citizen from Vietnam, recounted a similar sense of ambivalent belonging as an Australian. My thinking has become Australian. Mai's last comment could imply that she thinks that being Australian and being Asian are mutually exclusive. However, it appears that not all Australians of Asian origin would agree, as a letter to the editor in The Australian 7 newspaper clearly demonstrates.
