I remember those scanners, too. You can approach the group who are apparently now known as Materials Australia https://www.materialsaustralia.com.au/ https://www.materialsaustralia.com.au/ and they should have an archivist or historian with access to period records and publications. Failing that, visit the state library in your state and request the assistance of a research librarian. They should be able to help you locate potential records or journals if it was ever discussed.
