Welcome to OII Australia – we promote human rights and bodily autonomy for intersex people, and provide information, education and peer support


Intersex people are born with physical, hormonal or genetic features that are neither wholly female nor wholly male; or a combination of female and male; or neither female nor male. The term intersex was first used by science in the early 20th century; historically, the term “hermaphrodite” was used.

Intersex variations or traits are always congenital and can originate from genetic, chromosomal or hormonal variations. Environmental influences such as endocrine disruptors can also play a role in some intersex differences. The term is not applicable to situations where individuals deliberately alter their own anatomical characteristics.

Intersex is not about sexual orientation; people with intersex variations have as diverse a range of sexual orientations as non-intersex people.

Intersex is not about transition or gender identity; we have as diverse a range of gender identities as non-intersex people. Intersex is primarily about the body, although intersex people may have an identity that is contingent on our embodiment and natural sex characteristics.

Although figures vary, intersex people represent a significant percentage of the population.

Intersex people, especially those of us who are diagnosed at birth or in infancy, are often the subject of surgical or hormonal interventions to “fix” our sex and make us appear male or female. This is still considered “therapeutic” in Australia, with “psychosocial” rationales. We strongly contend this; there is no firm evidence supporting such interventions.

Organisation Intersex International Australia Limited (OII Australia) is a national body by and for people with intersex variations. We promote the human rights, self-determination and bodily autonomy of intersex people in Australia, to help us all achieve our maximum potential. We develop policy, and provide peer support, information and education. Our goals are to help create a society where sex differences are not stigmatised, and where our rights as people are recognised.

We have made significant contributions to Australian human rights policy and practice, resulting in:
