The announcement was generally welcomed by other politicians, including by the leader of the federal Opposition, Peter Dutton; Mostyn's colleagues; several women's advocacy organisations; the AFL; the Vietnam Veterans Association of Australia; the president of the Law Society of New South Wales; the incumbent governor-general, David Hurley, and oth
ers.
Commentators such as Sky News Australia host Chris Kenny and former executive director of the libertarian think tank Institute of Public Affairs, John Roskam, politician Pauline Hanson, and conservative lobby group Advance Australia, criticised the appointment owing to her past activism, which included having referred to Australia Day as "Invasion
Day" in subsequently-deleted social media posts, support for the Indigenous Voice to Parliament, which was rejected in the 2023 referendum, and expressing support for Australia becoming a republic.
ABC journalist Annabel Crabb observed that it was rare for such an appointment "to generate vicious denunciations on day one", arguing against News Corp journalist Janet Albrechtsen's denunciation of the appointment as being gender-based.
