Prior to the UN, Harriet was a senior strategist with Purpose, a consultancy advising NGOs like the Gates Foundation, WHO, Oxfam, Doctors of the World, and UN Environment on challenges from extreme poverty to renewable energy. She worked on Years of Living Dangerously, James Cameron’s Emmy-winning series about climate change for National Geographic and Showtime, and is the winner of the 2016 Wildcare Nature Writing Prize and the 2018 Emergence Creative Festival Screen Prize. She has been published in The Guardian, The Australian, The Diplomat, Island Magazine and Best Australian Essays.

Harriet holds a Masters in Investigative Journalism from Columbia University and studied International Security and Intelligence at Cambridge University under former head of MI6 Sir Richard Dearlove, where she researched the influence of the intelligence community on climate policy. As an undergrad, she studied climate change and international relations at the Australian National University and the University of Copenhagen in Denmark.

Harriet has sold five screenplays all of which focus on themes informed by her work in the NGO sector. Her first feature, a comedy about radical climate activists, is currently in development with the state film agency in Australia. In 2021 she was part of the Faber Academy programme working on her first novel (also about climate change). She comes from the rugged south coast of Western Australia.
