Passed in 1992, the Disability Discrimination Act (DDA) is a comprehensive australian act whose goal is to prevent discriminating against a person in many areas of public life, including employment, education, getting or using services, renting or buying a house or unit, and accessing public places, because of their disability.
Quoting the Australian Human Rights Commission, the DDA covers people who have temporary and permanent disabilities; physical, intellectual, sensory, neurological, learning and psychosocial disabilities, diseases or illnesses, physical disfigurement, medical conditions, and work-related injuries. It extends to disabilities that people have had in the past and potential future disabilities, as well as disabilities that people are assumed to have.
The DDA has a significant impact on web accessibility as well; in fact, it requires government agencies and their websites to provide information and services without discrimination. Today they are also required to meet the Web Content Accessibility Guidelines (WCAG) Level AA.
