Gender diversity in Australian astronomy: the Astronomical Society of Australia 1966–2023

Abstract

In this paper we examine the changes in the diversity of astronomers working in Australia, particularly the ratio of women compared to men, from 1966, when the Astronomical Society of Australia (ASA) was formed, to 2023. This was a pivotal time, as there was a significant change to workplace law that enabled women who worked for Commonwealth departments to retain their permanent position once they married. We consider the impact on gender diversity and other marginalised groups in astronomy due to this and other changes in the law, through the membership records of the ASA. We focus on the experiences of female astronomers who have been at the leading edge of change, and women and men who have instigated strategies to increase the percentage of women employed in astronomy. The successes of two Australian Research Council (ARC) centres of excellence in achieving gender balance are considered as providing best practice models.
