Rigorous, independent research on cities and the outer suburbs underpins the work of the NGAA. We are committed to regularly updating data on a range of issues facing our areas, from the challenges such as infrastructure backlog, to the solutions, including a fund for outer suburbs.

"Where you live has a huge impact on your quality of life – on how easy or hard it is to get to your job if you have one; how long it takes to get your child to hospital if you need to; how much time spent in your car or on congested roads or on overcrowded public transport takes you away from family and friends."

Transformational Infrastructure Projects in Australia’s Fast Growing Outer Suburbs

Transformational Infrastructure Projects in Australia’s Fast Growing Outer Suburbs identifies projects that have, or could, provide the basis for growth area councils to restructure economic and community functions. This report includes a variety of projects, including passenger rail linking population growth in the employment hubs, the redevelopment and repurposing of Council assets to create dense activity centres, a coordinated set of strategies to reshape and integrate a growth area, and health and education precincts.

Access to Employment

Improving access to employment is vital, either through providing more local jobs or better access to employment in other areas, particularly by public transport.

Innovation is needed

Innovation in the planning and delivery of town centres and regional transport is a major opportunity to address challenges arising from rapid population growth.

Critical role of local government

Local government has a critical role in the long-term strategic approaches required to develop and implement transformational projects.

Federal and State Government support is needed

While the role of Local Government is critical, the scale of transformational projects requires the support of Commonwealth and State Governments.

State of Australia's Fast Growing Outer Suburbs

The fast growing outer suburbs are in transition, economically as well as demographically. Their populations and their economies are becoming more diverse. Their economic and housing role has become even more important against the backdrop of rapid economic growth of our cities, agglomeration, and the rise of knowledge and services. They play a pivotal role in supporting both city centres on the one hand and rural townships on the other.


Economic transition

The fast growing outer suburbs are in transition.

City building role

Increasingly important against the backdrop of rapid economic growth of our cities, agglomeration, & the rise of knowledge/services.

Strong economic performance

The fast growing outer suburbs are performing strongly against economic, employment and population indicators. Exciting opportunities are emerging.

Investment to enable the opportunities

But investment is required to lay the foundation to ensure this transition is sustainable into the future.

Meeting Growth Area Infrastructure Investment Needs

Infrastructure access benchmarking analysis measured the required expenditure per person to give NGAA Member Council areas the same access to health and transport infrastructure as their inner-city neighbours.

The research, undertaken for NGAA by SGS Economics and Planning in November 2015, showed a $50 billion dollar backlog in residential care, hospitals, passenger rail and roads, with a further $23 billion needed to 2031.

Dedicated Infrastructure Fund for Australia's Outer Suburban Growth Areas

A review by PwC of national and international examples of dedicatedinfrastructure funding, showed that precedents exist to consider an outcome-driven infrastructure fund that could assist in providing the economic and social infrastructure Australia’s outer suburban growth areas need to prosper and enhance economic growth. Case studies include UK City Deals and Canadian Strategic Infrastructure Fund. The research also looked at potential impact on the Gawler rail line and the Epping to Chatswood Rail Link.
