In 2016 WiA broadened its aims to encompass wider issues of diversity. This expansion of the chapter’s remit was accompanied by a new name to reflect the change: Inclusion, Diversity and Equity in Astronomy (IDEA). The overarching objective of the IDEA Chapter is to achieve an environment in all institutions associated with Australian astronomy that is welcoming and supportive of all academic staff, professional staff and students, regardless of gender and sexual identity, ethnic and cultural background, disability, age, family/carer responsibilities, political affiliation, and religious belief.
