Australia, like other western nations, is experiencing a downturn in the proportion of females choosing higher education Information Technology (IT) courses. In the past this was not always the case although there were differential participation rates within the different streams of the IT field of study. This paper will present enrolment trends in the more technical to least technical IT streams. It will then discuss some emergent theories accounting for the declining popularity of IT with young women. Finally, an Australian model of mitigating circumstances and influences that impact on female career and course choices will be presented, with particular reference to females and IT.
