In this episode, we touch on energy, infrastructure and the political lens through which we receive nation-building ideas. We talk about Jay Weatherill, the South Australian Premier, who gave a master class this week in how to make federal ministers squirm. We also ask whether it is possible for journalists to remain neutral, a quarter into the Trump presidency.
