From its earliest beginnings, Bayesian statistics has been a synthesis of theory, methodology, computation and application. In this presentation, I will reflect on the development of the award-winning Australian Cancer Atlas (https://atlas.cancer.org.au/) and spotlight its Bayesian foundations. I will highlight some of the challenges and proposed solutions to modelling and visualisation of an awkward spatial geography, “filling in” missing covariates, and communicating uncertainty. I will also touch on new research directions inspired by the Atlas: new spatio-temporal models, spatial vulnerability indices, meta-analysis transfer learning, distributed AI and responsible data science. Importantly, these methodological discussions will be complemented by reflections on the impact of the work for patients, health practitioners, cancer support groups and government agencies. Bayesian statistics really can make a difference!
