HIV (Human Immunodeficiency Virus) is a virus that weakens the immune system.
HIV is covered by the definition of disability in the Disability Discrimination Act. The Act makes it against the law to discriminate against a person because of disability. There are some limited exceptions and exemptions.
Discrimination is against the law in many areas of public life including: employment, education, getting or using services, renting or buying a house or unit and accessing public places or facilities.
Example: A bank refused to offer a loan to an applicant unless they made a disclosure of their HIV status. This could be disability discrimination.
It is also against the law to discriminate against a person because of sexual orientation. There are some limited exemptions.
