What two main problems is the ‘three cities’ aspect of the Greater Sydney plan expected to solve?

The 'three cities' aspect of the Greater Sydney plan is expected to solve two main problems:

1. Congestion and Overpopulation: By dividing Sydney into three cities, the plan aims to distribute the population more evenly. This would reduce congestion in the city center and make the city more manageable in terms of infrastructure and services.

2. Accessibility and Equality: The second problem the plan aims to solve is the lack of accessibility and equality in terms of jobs, housing, and services. By creating three cities, each with its own centers of business and culture, the plan aims to ensure that all residents have easy access to these necessities, regardless of where they live.
