Think of a history textbook you had at school. Could you relate to the characters inside its pages? These women are proving Australian history contains multitudes. You just have to go looking for the version of Australia that never made it into the textbooks.
Meet four women reshaping how and whose history is told. Hidden histories with a Wiradjuri woman and nurse turned oral historian, a South Indian finance student turned storyteller, a Zambian born film-maker and author, and the founder of She Shapes History.

The ocean sustains all life on Earth, yet we know remarkably little about it. Now, because of technological advances, we could be on the cusp of a new age of exploration. But the ocean is in trouble.
As National Geographic's Chief Science and Exploration Officer and deputy administrator for the US National Oceanic and Atmospheric Administration, Terry Garcia has seen the worst humans can inflict on the environment, working on responses to major disasters the Exxon Valdez oil spill in Alaska and BP's Deepwater Horizon oil spill in the Gulf of Mexico. He says that in order to save the ocean, we need to understand it, and in order to understand it, we need to explore it.

It's the greatest power you all have as human beings — a healing power: to make others feel safe and welcome. It's so powerful because it puts a stop to their fears. The way to do this is learning to regulate your own fear responses. It's crucial to any relationship, but nowhere more so than in the therapy room. Fear makes or breaks successful therapy.
Recorded at the York Festival of Ideas and presented by the Complex Trauma Institute. The festival is led by the University of York, UK.
