in Australia since 9 December 2017. The Marriage Amendment (Definition and Religious Freedoms) Act 2017 permits any "2 people" to marry. Prior to that date, marriage was only permitted between a "man and a woman", meaning that intersex people who had other sex classifications, or sex classifications that matched their partner, could not legally marry each other. Historically, two legal cases are known to involve the marriages of intersex people. In the early twentieth century, the marriage of missionary Florrie Cox was annulled due to "malformation frigidity". In 1979, the Family Court of Australia, annulled the marriage of an intersex man, who had been "born a male and had been reared as a male" on the basis that he was an hermaphrodite. Right to life Intersex Peer Support Australia and Intersex Human Rights Australia have expressed concerns about the use of genetic selection via preimplantation genetic diagnosis, including in submissions to the National Health and Medical Research Council recommending that deselection of embryos and foetuses on grounds of intersex status should not be permitted. The organisations have also expressed concern about pregnancy termination rates of up to 88% in 47,XXY in circumstances where the World Health Organization describes the intersex trait as "compatible with normal life expectancy", and "often undiagnosed". In 2016, Intersex Human Rights Australia wrote about the sponsorship of lesbian, gay, bisexual, transgender and intersex (LGBTI) events by IVF clinics in Australia, stating that, in addition to ethical issues raised by the elimination of intersex traits, "sponsorship of "LGBTI" events by such businesses raises more ethical issues still, including the nature of community and comprehension of issues relating to intersex bodily diversity." Rights advocacy Notable intersex rights organizations in Australia include Intersex Human Rights Australia (formerly OII Australia) and Intersex Peer Support Australia (formerly Androgen Insensitivity Syndrome Support Group Australia).
