Wilfred Kelsham Fullagar was born in 1892 in Malvern, Victoria, and was educated at Scotch College and the University of Melbourne, where he studied arts and law with distinction. His academic achievements were interrupted by service in the First World War, during which he was wounded in France. After the war he completed his studies and was admitted to the Victorian Bar in 1922. From the outset of his career, Fullagar’s intellect and depth of learning marked him as a barrister of unusual promise.

He practised in a wide range of fields, but it was in equity, trusts, and constitutional law that he became most highly regarded. Fullagar had a particular gift for analysis and exposition. His written arguments were admired for their clarity, precision, and elegance, and he had a remarkable ability to distil complex legal problems into their essential parts. He rarely raised his voice in court, but his submissions were received with quiet attention because they were always anchored in deep principle and careful reasoning.

By the 1930s he was widely recognised as one of the leading minds at the Victorian Bar. He took silk in 1933 and increasingly appeared before the High Court, often in cases involving fundamental constitutional questions. His style was restrained, even austere, but his authority in legal argument was rarely challenged. Fellow barristers admired not only his formidable intellect but also his fairness and modesty. He was known for refusing cases where he believed the law was being twisted to serve interests he could not support in good conscience.

In 1945 Fullagar was appointed to the Supreme Court of Victoria, and five years later he was elevated to the High Court of Australia. His judgments on that bench confirmed what many had already believed—that he was among the finest legal minds the country had produced. His opinions were rigorous and often elegant, combining scholarship with a strong sense of legal coherence.

Fullagar served on the High Court until his death in 1961. His legacy remains in the clarity of his judgments, the influence of his advocacy, and the standard he set for what legal reasoning could achieve when pursued with honesty, restraint, and intellectual precision.
