Passage: Gillard attended Mitcham Demonstration School before going on to Unley High School. She began an arts degree at the University of Adelaide, during which she was president of the Adelaide University Union from 1981 to 1982. In her second year at the university, Gillard was introduced to politics by the daughter of a state Labor minister. Accordingly, she joined the Labor Club and became involved in a campaign to fight federal education budget cuts. Gillard cut short her courses in Adelaide in 1982, and moved to Melbourne to work with the Australian Union of Students. In 1983, she became the second woman to lead the Australian Union of Students, serving until the organisation's discontinuation in 1984. She was also the secretary of the left-wing organisation Socialist Forum. Having transferred her studies to the University of Melbourne, Gillard graduated with a Bachelor of Laws degree in 1986 and a Bachelor of Arts degree in 1989. In 1987, she joined the law firm Slater & Gordon in Werribee, Victoria, working in industrial law. In 1990, she was admitted as a partner; at the age of 29, she was the youngest partner within the firm, and one of the first women to hold the position.
