Attorney-General of Australia in the context of Attorney-General's Department (Australia)

William Morris Hughes (25 September 1862 – 28 October 1952) was an Australian politician who served as the seventh prime minister of Australia from 1915 to 1923. He led the nation during World War I, and his influence on national politics spanned several decades. He was a member of the federal parliament from the Federation of Australia in 1901 until his death in 1952, and is the only person to have served as a parliamentarian for more than 50 years. He represented six political parties during his career, leading five, outlasting four, and being expelled from three.

Hughes was born in London to Welsh parents. He emigrated to Australia at the age of 22, and became involved in the fledgling Australian labour movement. He was elected to the New South Wales Legislative Assembly in 1894, as a member of the New South Wales Labor Party, and then transferred to the new federal parliament in 1901. Hughes combined his early political career with part-time legal studies, and was called to the bar in 1903. He first entered cabinet in 1904, in the short-lived Watson government, and was later the Attorney-General of Australia in each of Andrew Fisher's governments. He was elected deputy leader of the Australian Labor Party in 1914.

Herbert Vere "Doc" Evatt (30 April 1894 – 2 November 1965) was an Australian politician and judge. He served as a justice of the High Court of Australia from 1930 to 1940, Attorney-General and Minister for External Affairs from 1941 to 1949, and leader of the Australian Labor Party (ALP) and Leader of the Opposition from 1951 to 1960. Evatt is considered one of Australia's most prominent public intellectuals of the twentieth century.

Evatt was born in East Maitland, New South Wales, and grew up on Sydney's North Shore. He studied law at the University of Sydney, attaining the degree of Doctor of Laws (LL.D.) in 1924. After a period in the New South Wales Legislative Assembly (1925–1930), Evatt was appointed to the High Court in 1930 by the Scullin government. He was 36 years old, and remains the youngest appointee in the court's history. He was considered an innovative judge, but left the court to seek election to federal parliament at the 1940 federal election.
