In September 2018, Australia hosted the 19th International Microscopy Congress in Sydney. As part of this conference, more than 600 teachers and students from 19 classes across the state of NSW were hosted on-site at the IMC19 Outreach Learning Space. The program resulted from a year-long collaborative effort between Australian Microscopy and Microanalysis and Microscopy Australia volunteers, academics, microscopy industry vendors, conference coordinators, STEM secondary school teachers, and local attractions. A unique feature of the program was the incorporation of the Australian national curriculum into the program via teacher-designed prework and postwork, helping to contribute to an award-winning conference.
