A megacity is defined as city with 10 million inhabitants or more. The population of Melbourne is projected double over the next 40 years, from 5 million to 10 million people. This growth in population will be accompanied by a major growth in the urban fabric of Melbourne, and those in the design industries will play a central role in determining the type of city Melbourne will become. This exhibition presented ideas and propositions for Melbourne’s future as a megacity from an array of local designers, architects, urban planners and thinkers.
