Includes minutes (1922-1984), reports, agenda and decisions, financial records, correspondence, subject files, newspaper clippings, and photographs.
Papers relate to : industrial disputes, Cosme colony, the Eight Hour Day Movement, Communist Party of Australia (Queensland) and Australian Labor Party, Workers' Educational Association, Australian Labor Day Committee, Queensland Industrial Court, Trade Union congresses, and Australian Council of Trade Unions.
