In late 1991, the Australian Society for Immunology Incorporated merged with the New Zealand Society for Immunology (founded in 1975) to form the Australasian Society for Immunology Incorporated. Covering the full scope of immunology in humans and animals, the Society was formed to encourage and support the discipline in the Australasian region.

In 1988, the Australian Society for Immunology became incorporated, creating a new legal entity which allowed the Society to act as a group, as opposed to a collection of individuals.

The Australian Society for Immunology, or ASI (first called the Australian Society of Immunologists) was formed as a national society in 1970, following less formal meetings of Australian immunologists in the 1960s. ASI was established as a means of providing interaction and communication between immunologists in Australia.

The Honorary Secretary of the Australian Society for Immunology (later, the Australian Socety for Immunology Incorporated, and the Australasian Society for Immunology Incorporated after that) was responsible for dealing with the professional records of the Society. For example, the Honorary Secretary dealt with conference records, reports, professional correspondence with individuals (including Society Members) and organisations, membership records and so forth.

The Secretariat was created by the Australian Society for Immunology in 1984 to perform administrative and secretarial functions, including dealing with the day to day interactions of the Society, general correspondence, accounts, and other similar duties.

Professor William J. (Bill) Halliday was appointed an Honorary Life Member of the Australasian Society for Immunology Incorporated in c.1992, due to his significant contributions to the field. Professor Halliday donated papers to the Society archive from the 1969 symposium "Aspects of Antibody Formation and Unresponsiveness", the first meeting to be held under the name "The Australian Society of Immunologists".

Associate Professor Ian Frazer was a councillor for the Queensland Branch of the Australasian Soceity for Immunology Incorporated (ASI Inc.) at the time he donated papers from the Queensland Branch to the ASI Inc. archives.

Dr. Harry Ward was a member of the Australian Society of Immunologists and its successor organisations for many years, attending the First Annual Meeting of the Society in 1971. In 1993, when the role of Honorary Archivist was created for the Australasian Society for Immunology Incorporated (ASI Inc.), Dr. Ward was appointed to the position, which he held until late 1997. In 2000, he contributed further material to the collection, including some of his own files, as well as papers sent to him by other members of ASI Inc.

Dr. Roland Scollay was Vice President of the Australasian Society for Immunology Incorporated (ASI Inc.) in 1992 (under President Geoff Shellam), President of ASI Inc. in 1993 and 1994, and Past President in 1995.
