    Collection in context

    The information in this index was gathered by officials working for the Australian Securities and Investments Commission. The index is a secondary source derived from the Australian Business Register, which is a primary historical source. The original documents are maintained by the Australian Securities and Investments Commission.

    The registration of businesses was controlled by the states until 1990. The federal government took over when the Australian Securities and Investments Commission was established on 2 January, 1991.

    Australian Company Numbers (ACN) and Australian Business Numbers were instituted by the Corporations Act of 2001. The ACN is issued only to companies, while the ABN is issued to sole proprietors, partnerships, and companies. The ACN is a nine-digit number and the ABN is an 11-digit number in which the last nine digits are usually the same as the ACN.
