Science podcasts have become an increasingly popular channel for science communication. Although podcasting has risen in popularity, little is known about why science podcasters choose to pursue this pathway for communication and how they set about achieving their goals for their podcast. Drawing on qualitative data from interviews with 20 science podcasters in Australia, our results reveal that the podcasters are mainly driven by personal factors such as their interest in, enjoyment of, and curiosity about science and that while they employ various tactics to achieve their goals, they do not consciously consider these tactics to be a form of strategic science communication.
