It is our milestone 20th episode! To make it a bit special this time we have two guests. They share their views on cooperative ownership as a sustainable solution to the housing affordability crisis. Jason Twill, the director of Urban Apostles, focuses on how the sharing economy can interlace with art of city making. Chels Marshall, a PhD candidate at ANU, explores land ownership of Indigenous people and how modern society could successfully transcend from being sustainable to regenerative.
