parenting in Australia is legal nationwide, with the Northern Territory the last jurisdiction to pass an adoption equality law in March 2018. Discrimination on the basis of sexual orientation and gender identity or expression is prohibited in every state and territory, with concurrent federal protections for sexual orientation, gender identity and intersex status since 1 August 2013. Transgender rights in Australia and intersex rights in Australia vary between jurisdictions, with QLD and NSW legally requiring a person to undergo sex reassignment surgery - before changing the legal sex on birth certificates. Non-binary Australians can legally register a "non-specific" sex on federal legal documents and in the records of some states and territories. Summary table Social conditions Public attitudes A 2005 paper by the Australia Institute, Mapping Homophobia in Australia, found that 35% of people aged 14 or above considered homosexuality to be immoral, with Queensland and Tasmania having the highest levels of anti-gay sentiment and Victoria the lowest. Overall the most anti-LGBT areas in the study were the Moreton area of country Queensland (excluding the Gold Coast and Sunshine Coast), Central and South-West Queensland and the Burnie/Western district of Tasmania, where 50% considered homosexuality to be immoral, while the least homophobic were inner-city Melbourne (14%), central Perth (21%) and central Melbourne (26%). A 2018 Ipsos survey of the attitudes towards transgender people in several countries found 71% of Australian respondents thought that the country was becoming more tolerant of transgender people. Indigenous LGBTI community Gender diverse and transgender Aboriginal Australians and Torres Strait Islanders are often referred to as sistergirls and brotherboys. The level of acceptance varies with each community and its elders. In 2015, Dameyon Bonson established Black Rainbow as a mental health support and suicide prevention service for LGBTI Indigenous Australians, given that they often suffer dual discrimination through both racism and homophobia/transphobia, and are 45 times more likely to commit suicide than the general population.
