For those who cannot describe themselves as either male or female the Australian passport system has now come up with an answer. They have created another gender option called x. The new category will be used for intersex people, those who are neither biologically male nor female. Transgendered passport holders, however, those who have changed gender will be free to choose either male or female but not allowed to select x. Previously travellers were not allowed to change the sex on their passports unless they had undergone surgery. This is still the case in many other countries. In Britain people do not need to have had an operation in order to change the sex on their passport they must just have evidence that they are permanently living in a new gender role.
