Unwanted Australians (Part 1)

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. An investigation by SBS has found they're among hundreds of migrants given adverse security records and refused naturalisation and, together with their communities, kept under sustained surveillance by Australia's domestic spy agency, ASIO. Their supporters include one of Australia's most eminent legal minds, former High Court Judge Michael Kirby, who argues that some "remedial action" is justified.
