children aged less than 12 years old, or persons participating in coaching, refereeing, or administering sporting activities. Tasmania has also passed legislation precluding discrimination on the basis of intersex status, and similar legislative amendments passed in the Australian Capital Territory and South Australia, went into full effect in 2017. Furthermore in 2019, Tasmania replaced the attribute of intersex status with the more internationally accepted attribute of sex characteristics, becoming the first Australian jurisdiction to do so. Intersex Human Rights Australia has expressed concern about a lack of public awareness of these protections. Research on intersex Australians published in 2016 shows that, while 2% of Australians fail to complete secondary school, 18% of Australians born with intersex variations fail to do so due to issues around bullying, discrimination and pubertal medical interventions. In 2014, Intersex Human Rights Australia and Pride in Diversity partnered to publish a guide on intersex employees for employers. Identification documents Australian research has shown that 19% of people born with atypical sex characteristics selected an "X" or "other" classification, while 52% are women and 23% men and 6% unsure. Alex MacFarlane received the first Australian passport with an 'X' sex descriptor, reported in January 2003. Australian 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 the availability of the X descriptor to all individuals with documented "indeterminate" sex. From 2013, federal guidelines enable all people to identify gender as male, female or X on federal documents, including passports. Documentary evidence must be witnessed by a doctor or psychologist, but medical intervention is not required. In Australia, birth certificates are issued by States and Territories. Intersex Human Rights Australia states that identification changes are managed as an administrative correction. Alex MacFarlane is also believed to be the first person in Australia to obtain a birth certificate recording sex as indeterminate, reported in January 2003. In March 2017, an Australian and Aotearoa/New Zealand community statement called for an end to legal classification of sex, stating that legal third classifications, like binary classifications, were based on structural violence and failed to respect diversity and a "right to self-determination".
