The Science Threshold Learning Outcomes (TLOs) are a consensus set of academic standards for Australian university Science education. They were developed by Prof. Brian Yates and Prof. Sue Jones, supported by Dr Jo-Anne Kelder, during 2010–2011. The co-authors of this paper are key figures in Australian Science education, and in this manuscript, we have used a reflective semi-structured interview approach to describe the process of developing the Science TLOs and consider their subsequent effect on tertiary science education in Australia. This manuscript documents Sue and Brian’s impact on science curriculum through the lenses of leadership, community and practice. We have a twofold aim: first to draw lessons for harnessing consensus in scientific communities on the value and purpose of a tertiary science education, and second to celebrate the success of these influential and impactful leaders in our community. We demonstrate how work to develop the TLOs has transformed tertiary science education in Australia.
