Sally Joseph was one of the first solicitors to work at the Aboriginal Legal Service in Redfern, Sydney. She graduated from the University of Sydney with a Bachelor of Laws degree in 1967, the same year in which she was appointed to the Commission of the Peace for the State of New South Wales. Although admitted to the New South Wales Bar, Joseph did not practise as a barrister, instead working briefly at the Commonwealth Crown Solicitor's Office before being admitted as a solicitor on 11 February 1972. She practised at the Aboriginal Legal Service and later in the eastern Sydney suburb of Vaucluse.
