Many factors have influenced population density change in Australian cities over the past 30 years. Melbourne has led the way in inner-city rebirth as a way to help manage future growth.
Government and industry need to demonstrate the benefits of well-designed higher-density housing. Rich residential display projects may be the ideal catalyst for creating smarter cities.
If Perth can preserve the rich biodiversity of its setting, it will become a model for sustainable city development that fully connects with the value of natural ecosystem services.
