Her death was reported on 14 September 2026. She joined the court in 1987 at age 44 and served until 2003.

She was born on 5 January 1943 in Moree, New South Wales. She studied law at the University of Sydney on a scholarship. She built her early practice in defamation and industrial law. Defamation covers claims about damage to reputation. Industrial law covers workplaces, unions and employment disputes.

In 1972 she became the first woman appointed to the NSW Bar Council, the elected body that leads barristers in the state. That same year she argued the equal pay case before the conciliation and arbitration commission, the federal body that set wages and settled workplace disputes, much like an umpire for the labour market. Former Labor minister Clyde Cameron had chosen her to present the case for female workers. ABC In 1974 she was appointed deputy president of that commission. In that role she presided over a test case on maternity leave. Within three years she had moved from bar leadership to counsel in a national pay claim to senior member deciding leave rights.

Her elevation in 1987 placed her on the Mason court, led by Chief Justice Sir Anthony Mason. ABC She sat on the decision in Mabo v Queensland, the native title case about Indigenous land rights. Susan Crennan later became the second woman to sit on the bench after Gaudron. Gaudron stayed from 1987 to 2003, spanning the late Mason years and the Gleeson years. The period involved much constitutional and federal work.

After leaving the court in 2003, she joined the International Labour Organization in Geneva. She became president of its administrative tribunal, the panel that decides employment disputes involving staff of international organisations.

An earlier detail places her in a longer legal lineage. She was once handed a copy of the Australian Constitution by Bert Evatt. High Court

The broader context here is continuity across those postings. She argued equal pay before the commission, then decided maternity leave as deputy president, then decided native title and other federal matters as a High Court justice, then presided over staff cases as tribunal president. For lawyers who work across national and international systems, her career links three settings that are often studied apart: conciliation and arbitration, High Court appeals, and international staff adjudication.

Looking at what this means for the High Court, her 1987 appointment set the precedent for later appointments of women. Crennan followed as the second. Later benches have been measured in part against the break Gaudron made. Her papers, reasons and separate concurrences will now be reread for method, especially on equality, employment and native title, and for how a first appointment affects how a court works together.
