Mary Gaudron QC (1943-2026).

Mary Genevieve Gaudron was born on 5 January 1943 in Moree, in northern New South Wales, the daughter of working-class parents. She said in later life that the open racism toward Aboriginal people she saw in the town shaped a lasting opposition to discrimination. She died aged 83, her death announced on 13 September 2026. For the whole of the High Court's first century, she was the only woman to sit on it.

Her path to the law began with a question. In 1951, the former Labor leader H. V. Evatt passed through Moree during a referendum campaign, speaking from the back of a utility. The eight-year-old Gaudron asked him what a constitution was. He sent her a copy in the mail. When schoolmates called the pamphlet useless, she told them it was of great use to lawyers, and that one day she would be one. The account comes from Pamela Burton's biography, From Moree to Mabo: The Mary Gaudron Story.

From Moree to the New South Wales Bar.

Gaudron won a scholarship to the University of Sydney, taking a Bachelor of Arts in 1962 and then a law degree in 1965 with first-class honours and the University Medal. She was the second woman to receive the medal, after Elizabeth Evatt, and the first part-time student to do so. As a student she tried to obtain articles of clerkship and was turned away. She later recalled being told, by many senior lawyers, that it was not their policy to take on women.

She was admitted to the New South Wales Bar in October 1968 and practised in industrial and common law. When she tried to buy a room in barristers' chambers she was refused more than once because she was a woman, and she ended up sharing a room with Janet Coombs, another early woman at the Bar. In 1972 she became the first woman on the Council of the New South Wales Bar. One of her first appearances of note came in 1970, when at the age of 27 she argued a case single-handed in the High Court after the client dismissed his senior counsel and asked her to run it alone.

Equal pay, maternity leave, and the Arbitration Commission.

In 1972 Gaudron argued the Equal Pay Case for the incoming Whitlam government before the Conciliation and Arbitration Commission. The decision extended the principle of equal pay for equal work beyond the limited group of occupations covered by earlier rulings. She built the argument in part on the Equal Remuneration Convention of the International Labour Organization, a body she would work for decades later.

In April 1974 she was appointed a Deputy President of the Conciliation and Arbitration Commission. At 31 she was the youngest federal judicial officer of her day. Her best-known work there was the 1979 maternity leave test case, which set award standards allowing a year of unpaid leave for full-time and permanent part-time workers. She held the office until 1980, and for a period chaired the New South Wales Legal Services Commission.

First female Solicitor-General and Queen's Counsel.

In February 1981 Gaudron was appointed Solicitor-General of New South Wales. She was the first woman to hold that office in any Australian jurisdiction. In the same year she was made a Queen's Counsel, the first woman in New South Wales to take silk. As Solicitor-General she appeared for the state in major constitutional cases in the High Court, among them the Tasmanian Dams case, Commonwealth v Tasmania.

She spoke often about why the makeup of the courts mattered. In a University of Sydney address she said it was, in her words, "essential that our lawyers should be drawn from the entire social spectrum," because judges exercise wide discretionary powers.

Appointment to the High Court, 1987.

Two vacancies opened on the High Court after the death of Justice Lionel Murphy and the retirement of Chief Justice Sir Harry Gibbs. On 6 February 1987 Gaudron and John Toohey were appointed, on the nomination of the Hawke government. At 44 she was one of the youngest people appointed to the court, and its first woman. No other woman would join the court while it completed its first hundred years.

She sat through the period of the Mason and Brennan courts, which decided a run of cases that changed Australian law. In the Australia Day honours of 1988 she was offered appointment as a Companion of the Order of Australia, and she declined it, without giving a reason.

Mabo, Dietrich, and the judgments she is remembered for.

In Mabo v Queensland (No 2) [1992] HCA 23 the High Court held that native title survived British settlement and is recognised at common law. Gaudron joined a judgment with Justice William Deane. In it they wrote that the dispossession of Aboriginal people underwrote the development of the nation and left, in their words, "a national legacy of unutterable shame."

In Dietrich v The Queen [1992] HCA 57 she was in the majority that held that a person facing a serious charge who cannot get legal representation, through no fault of their own, should ordinarily have the trial adjourned or stayed until representation is arranged. The decision remains a foundation of the right to a fair trial in Australia, and it is cited in criminal courts to this day.

Her work reached across the law. She sat on Cole v Whitfield [1988] HCA 18, which settled the modern meaning of the free-trade guarantee in section 92 of the Constitution. She wrote on discrimination, including in Street v Queensland Bar Association [1989] HCA 53 on section 117, and in a joint judgment with Justice Michael McHugh in Castlemaine Tooheys Ltd v South Australia [1990] HCA 1. In criminal law she was known for holding trial judges strictly to their duty to direct juries correctly. Commentators noted that she wrote plainly and did not favour flourish.

Retirement, and the International Labour Organization.

Gaudron announced her retirement in 2002 and left the High Court in early 2003, at the age of 60, well before the mandatory retiring age of 70. She then joined the International Labour Organization in Geneva. She served as a judge of its Administrative Tribunal and was its President from 2011 to 2014. In 2004 she took part in an inquiry into trade union rights in Belarus.

She was the founding patron of Australian Women Lawyers from 1997, holding the role until 2009, and was placed on the Victorian Honour Roll of Women in 2001. Reflecting on her career, she once described herself as privileged, in her words, "to be a bit player in the maintenance of the rule of law in Australia."

In her own words.

Her public speeches, several of which the High Court has published, returned again and again to equality and the law. In an Occasional Address at the University of Sydney in 1999 she said that within her lifetime Australia had laid, in her words, "the foundations for what, hopefully, will one day become and remain a nation of true equals." In 2000 she spoke plainly about resistance to that idea, saying there were people who did not accept that men and women are equal and who feared the equal participation of women in the workplace.

Her speeches to launch Australian Women Lawyers in 1997, the 1999 University of Sydney address, and a 2002 address are collected on the High Court's website.

Tributes.

The Governor-General, Sam Mostyn, said on 13 September 2026 that Gaudron "broke new ground and inspired generations of Australians to pursue careers in the law and public service," and that she brought "fierce intellect, integrity, compassion and a deep commitment to justice" to every role she held. The Law Society of South Australia said she had made "an enduring contribution to public life through her advocacy for equality, her service to the legal profession and her role as a trailblazer for women in law." Her friend and former colleague Justice Michael Kirby had said years earlier that her early departure left the court, in his words, "a more blokey place."

She is survived by her three children, Danielle, Julienne and Patrick.
