Ongoing growth and shifting populations are reshaping Australian cities, raising urgent questions about scale and density.
Critical Mass asks: How can urban density become a catalyst for better city-making – less extractive, more cohesive, and more responsive to both people and planet?
Borrowed from nuclear physics, Critical Mass refers to the minimum needed to trigger a self-sustaining chain reaction. Drawing on global perspectives from leading international keynote speakers, this year’s Forum explores the tipping points where cities either thrive or fracture and how small deliberate shifts can spark big impacts amid rapid urban change.
