The fourth of five children of Isa May Wilson 'deserted wife', Beth Wilson grew up in Hastings, Victoria. She left school at age 15 because she had holes in her school shoes and no money to pay for new ones. Beth worked in shops, factories, fruit picking and fishing until she returned to night school at Prahran High School in 1970. Beth worked at Pict Frozen Pea factory in Nottinghill during the day. She was assisted by a Commonwealth Scholarship to Monash University and later, Gough Whitlam's abolition of university fees. At night school Beth met the feminist activist Mary Owen who became a dear friend and influence on her strong sense of social justice and women's rights.

At Monash Beth studied Arts and Law and later Librarianship at RMIT. She worked in the Library at Telecom and then as librarian/researcher to the Victoria Law Foundation and the Law reform Commission of Victoria. She is currently a mentor for Monash University students.

In the mid 1980s Feminist Lawyers was re-formed and Beth and her colleagues assisted two young women, Sandra and Tracey Collis who had been charged with perjury and jailed for withdrawing their claims of incest by their father. Convinced that these two young women were victims not offenders Feminist Lawyers worked with the Domestic Violence and Incest Resources Centre to launch a successful appeal to have the Collis sisters released from prison and later to have their convictions erased through a Pardon.

Feminist Lawyers sought the assistance of Barrister John Dixon (pro bono) and Fitzroy Legal Centre (Angela Palombo) to lodge a complaint to the then Solicitor's Disciplinary Board against the lawyer who represented the Collis sisters and their father. Not surprisingly the Board found there was a conflict of interest and upheld the complaint against Robert John Gallbally. John Dixon later assisted the Collis sisters in a civil suit against Robert Gallbally.

Beth worked in the legal and policy section of the Department of Health with Feminist Lawyers founder, Bebe Loff. It was an exciting time for policy as recent major reforms had been made with the establishment of the Heath Services Commissioner, the Guardianship and Administration Board and the Mental Health Review Board. She also joined the editorial collective of the Legal Services Bulletin that later became the Alternative Law Journal and she established its long running column 'Sit Down Girlie'.

Beth was appointed to the Social Security Appeals Board in 1985, the Workcare Appeals Board in 1990 and became President of the Mental Health Review Board in 1992. She is a past President of the Victorian Branch of the Australian and New Zealand Association of Psychiatry, Psychology and Law.

Beth also assisted the very brave Ercan Tekin, a man with cerebral palsy who had been 'ripped off' by a chiropractor who claimed to be able to 'cure' cerebral palsy with hyperbaric treatment. Ercan's story was featured on The Law Report ABC Radio National, 16 June 2009 and in Beth's exit interview on The Law Report on 11 December 2012).

In 2006 Beth led an Australian Delegation for HREOC assessing the progress of China's human rights obligations in family planning held in Urumqui, Xiang Jing Autonomous Region, North West China.
