The Genderqueer flag. The lavender stripe, mixing blue and pink (traditional male and female colors, also present on the trans flag) is meant to represent those under the GQ umbrella who feel they are both male and female in identity as well as “queerness.” Lavender has long been associated with homosexuality and bisexuality. Dark chartreuse green, the inverse of the lavender color, is meant to represent GQ individuals who feel they are neither male nor female in identity. The white stripe is meant to represent GQ individuals falling completely outside of the gender binary.
Genderqueer (GQ; alternatively non-binary) is a catch-all category for gender identities other than man and woman, thus outside of the gender binary and cisnormativity. Genderqueer people may identify as one or more of the following:
having an overlap of, or indefinite lines between, gender identity and sexual and romantic orientation.
without a gender (nongendered, genderless, agender; neutrois);
moving between genders or with a fluctuating gender identity (genderfluid);
third gender or other-gendered; includes those who do not place a name to their gender;
Some genderqueer people also desire physical modification or hormones to suit their preferred expression. Many genderqueer people see gender and sex as separable aspects of a person and sometimes identify as a male woman, a female man, or a male/female/intersex genderqueer person. Gender identity is defined as one's internal sense of being a woman, man, both, or neither, while sexual identity refers to an individual's enduring physical, romantic, and/or emotional attraction to others. As such, genderqueer people may have a variety of sexual orientations, as with transgender and cisgender people.
In addition to being an umbrella term, genderqueer has been used as an adjective to refer to any people who transgress distinctions of gender, regardless of their self-defined gender identity, i.e. those who "queer" gender, expressing it non-normatively.Androgynous is frequently used as a descriptive term for people in this category, though genderqueer people may express a combination of masculinity and femininity, or neither, in their gender expression and not all identify as androgynous. However, the term has been applied by those describing what they see as a gender ambiguity.
Genderqueer was one of 56 gender identity options added to Facebook in February 2014. 
In an analysis of respondents to the National Transgender Discrimination Survey who chose "A gender not listed here", the majority of whom are genderqueer, it was found that Q3GNLH (Question 3 Gender Not Listed Here) respondents were 9 percentage-points (33%) more likely to forgo healthcare due to fear of discrimination than the general sample (36% compared to 27%). 76% reported being unemployed, 90% had experienced anti-trans bias at work, and 43% had attempted suicide.
First reported in January 2003, Australians can use "X" as their gender. Alex MacFarlane is believed to be the first person in Australia to obtain a birth certificate recording sex as indeterminate, and the first Australian passport with an 'X' sex marker in 2003. This is stated by the West Australian to be on the basis of a challenge by MacFarlane, using an indeterminate birth certificate issued by the State of Victoria. The West Australian newspaper reported in January 2003 that the Department of Foreign Affairs and Trade "had decided to accommodate people whose birth certificates recorded their sex as indeterminate ... Alex is also believed to be the first Australian issued with a birth certificate acknowledging a gender other than male or female. Alex's says “indeterminate - also known as intersex”. It was issued in Alex's birth State of Victoria, which unlike WA, changed its policy to allow the category".
Government policy between 2003 and 2011 was to issue passports with an 'X' marker only to people who could "present a birth certificate that notes their sex as indeterminate".
In 2011, the Australian Passport Office introduced new guidelines for issuing of passports with a new gender, and broadened availability of an X descriptor to all individuals with documented "indeterminate" sex. The revised policy stated that "sex reassignment surgery is not a prerequisite to issue a passport in a new gender. Birth or citizenship certificates do not need to be amended."
Australian Commonwealth guidelines on the recognition of sex and gender, published in June 2013, now extend the use of an 'X' gender marker to any adult who chooses that option, in all dealings with the Commonwealth government and its agencies. The option is being introduced over a three year period. The guidelines also clarify that the federal government collects data on gender, rather than sex.
Also in 2013, people with non-binary gender identities received formal protection from discrimination, with the addition of a new attribute "gender identity" to anti-discrimination law.
Norrie May-Welby is popularly - but erroneously - often regarded as the first person in the world to obtain officially indeterminate, unspecified or "genderless" status. May-Welby became the first transsexual person in Australia to pursue a legal status of neither a man nor a woman, in 2010. That status is subject to an appeal by the State of New South Wales.
