P&P document cover


Australia’s largest multi-city region is being developed in New South Wales. Also known as a mega-region, a multi-city region establishes an integrated network of globally and locally connected cities.

An integrated network of globally and locally connected cities that harness scale and diversity can create an inclusive, resilient and globally competitive economy and region.

The project

An examination of the growing phenomenon of multi-city regions around the world, the Greater Cities: The Global Experience of Planning, Preparing and Promoting the Multi-City Region report is a collaborative research effort between the Greater Cities Commission and the Business of Cities. The report explores the social, environmental and economic benefits of a well-planned multi-city region.


  • Case studies from 10 global mega-regions, including Hong Kong, the Greater Bay Area, Seoul Capital Region (Seoul-Incheon), Singapore, the Kuala-Lumpur Corridor, and the Tokyo-Osaka Belt.
  • Data led insights into transport, coastal development, economic diversification and complementarity, and large-to-small city dynamics in the regions.
  • Collation of research findings to support development of the Multi-City Plan.
