McGlade has often acted as an advocate for
Indigenous Australians, especially focussing on issues relating to law,
sexual assault, women's justice and systemic discrimination. In 2002, she brought then-federal senator
Ross Lightfoot to court for
racial discrimination after he commented that Aboriginal Australians were "the most primitive race on earth". She was successful, and Lightfoot was charged with breaching the
Racial Discrimination Act 1975. In 2016, McGlade began campaigning for a stand-alone national action plan to address violence against women, and her advocacy was successful before a number of UN treaty bodies and expert mechanisms. In 2020 she called for a Council on Violence Against Aboriginal Women and Children in collaboration with the national body
Our Watch (founded by
Natasha Stott Despoja in 2013). In June 2021 the
Morrison government established a National Plan Advisory Group headed by
Marise Payne, Minister for Women, to "inform the development of the National Plan to end family, domestic and sexual violence in Australia". Her advocacy for Aboriginal women and children over decades led to the establishment of the first service in Perth for victims, named Djinda. While a cultural heritage bill was proposed in
Western Australian Parliament in 2021 which attempted to prevent such situations in the future, McGlade rejected its legitimacy and claimed Indigenous people had not been sufficiently consulted on the issue. With four other Indigenous people, she asked the
United Nations Committee on the Elimination of Racial Discrimination to review the bill, claiming it contradicted Australia's international obligations regarding racial discrimination. Also in 2021, she voiced concerns about
Bruce Pascoe's book
Dark Emu, saying that it was "ideological and subjective", "not very truthful or accurate" and "misleading and offensive to Aboriginal people and culture". ==Other roles==
