text:  Immigration lawyer Jan Gothard explained. Most people think of the white Australia policy or immigration restriction in terms of people of colour and those racist provisions have been removed. The Racial Discrimination Act meant, in theory, the end to racial discrimination but the Disability Discrimination Act did not get rid of the disability and health discriminations which were set up in 1901. So really it's an historical thing. We still treat people with disability in the same way as we did in 1901 and we think they're not people who are welcome in Australia.
