Situated City: Action Exchange was a mobile discussion space parked on Prototype Street as part of Melbourne Knowledge Week 2019. Millie Cattlin (The Projects) and Lynda Roberts (Public Assembly) took part in series of short, action-based discussions with invited guests in the pop-up Public Field Office: How do creatives interact with the shared spaces of our city? How do they work in and around civic systems? and what do they consider to be the key ideas for the future?
