A group of elderly migrant Australians is calling for official acknowledgment they were unfairly treated by past governments after being denied citizenship on political grounds for decades after World War Two.
A major SBS investigation using previously-classified documents from the National Archives of Australia has revealed that hundreds of migrants were denied citizenship for decades on political grounds.
Other measures put forward to deal with terrorist suspects in the 21st century - including deportation, detention or restricted movements - have also been used against migrants because of their known or suspected political leanings, usually as Communists.
The action against these migrants took place from the 1950s to 1970s, but details of what happened to them have in most cases only just come to light as their previously secret files have been declassified.
The SBS investigation has shown official treatment of these so-called "Unwanted Australians" has had extensive and, in many cases, severe detrimental effects on them.
In this first of a two-part series we look at the extensive consequences experienced by these "Unwanted Australians".
