The Australian Government has guidelines on the recognition of Sex and Gender. They are available on the Attorney General's website : http://www.ag.gov.au/Publications/Pages/AustralianGovernmentGuidelinesontheRecognitionofSexandGender.aspx .
In particular the guidelines provide that where sex and/or gender information is collected and recorded in a personal record by a government agency, individuals should be given the option to select M (male), F (female) or X (Indeterminate/Intersex/Unspecified).
The guidelines also provide the processes for changing Sex or Gender information in government records.
