Abstract. 1969: the year of the first moon landing (20 July), the Woodstock Festival in upstate New York (15–18 August), and, (coinciding with the last day of Woodstock!), the beginning of the Australasian Plant Pathology Society [first annual general meeting at the 41st Australian and New Zealand Association for the Advancement of Science meeting, Adelaide (18 August) (Purss 1994)]. All had a lengthy gestation and challenges along the way. All have changed the world! In the 17th President’s Address to the Australasian Plant Pathology Society, David Guest (2001), noted: ‘I became a plant pathologist because the mechanisms organisms use to communicate fascinate me’. Well, I became a plant pathologist because I am a gardener at heart. But I have learned along the way that communication is a critical issue – not only the communication among and between microorganisms and plants, but also that between plant pathologists, farmers, politicians and communities. And, communication that is timely, inspiring and, (preferably) accurate, often yields the most favourable outcomes. In this paper, I will explore some of the early communication relating to plant disease, particularly wheat rusts. I refer to Erasmus and Charles Darwin, Joseph Banks, Thomas Knight, and some pioneering Australian researchers, and the roles of conferences, publications and newspapers, to highlight how ‘getting our message out’ was as important in the 19th and early 20th centuries as it is now. And, finally, I will consider how a scientific society in the 21st century still has relevance and the potential to change the world.

They further suggest that use of the abstracting services, compendia, reviews, online access) are CABI Compendia (crop protection, etc.) resulted in annual both important. median time savings of between 37 and 54 days per user, Compared with today, two centuries ago, information that representing a national saving of between AUS$940 000 and was used for deciding how a plant disease might be controlled AUS$1.38 million per year. These demonstrate the economic was much lessaccurate and reliable(even the ideaof ‘disease’ was benefits of easily accessing knowledge, and inter alia of ensuring unclear). Information was difficult to access, and there were an ongoing supply of new and current information. But, which large gaps between ‘facts’. Credit is shared among curious knowledge is most valuable – recent or older information? And, (independently wealthy) individuals and influential what benefits accrue from the investment by scientific societies in powerbrokers, the development of printing and microscopy, peer review, publication and conferences, to ensure the ongoing the emergence of scientific societies, coffee houses, market supply of accurate and reliable knowledge for future users? days, sheep shearings and other informal forums, during the An insight into the use that plant pathologists make of the ‘Age of Enlightenment’ (Gascoigne 1994; Goddard 2000), for information obtained in literature reviews and the scientific supporting the emergence of many fields of science, the literature was provided by Parbery (2008).
