The collection contains material assembled by the Plea for Justice Committee and the National Freedom Council in the course of their campaigns to promote justice for the Chamberlains. It includes correspondence, transcripts, reports, submissions, debates, articles, media releases, newspaper cuttings, books, 6 video cassettes and 5 audio cassettes. Correspondents include Lindy and Michael Chamberlain, the Commonwealth Ombudsman, the Human Rights Commission, members of the public who supported the Chamberlains, and church ministers and pastors. The collection includes documents produced by the Chamberlain Innocence Committee. There are a number of miscellaneous journals that contain articles about the Chamberlain case, including some published by Christian organisations.
The National Freedom Council, established in 1984, grew out of the Plea for Justice Committee which formed in the wake of Lindy Chamberlain's conviction and life sentence in 1982. The Committee sought a judicial review of the Chamberlain case and that Lindy Chamberlain be released from prison pending the outcome of that review. The Council was also involved in other cases where forensic science and circumstantial evidence had majored in convictions.
