About the NGAA

Our Vision

The NGAA works with, and on behalf of, our Councils to achieve our vision for Australian cities where residents have equitable access to housing, jobs, education, health services, cultural activities and the physical and community infrastructure that support these outcomes – no matter where they live. 

Our Role

NGAA is the peak body for local governments in Australia’s outer metropolitan growth areas and advocates to state and federal governments on growth area challenges and opportunities. Together, we represent more than five million people living in Australia’s fast-growing suburbs and are united by shared experiences of population growth rates at double the national average and long-term under-investment in vital infrastructure.

We take an evidence-based approach, with a Policy Platform built on the foundations of our comprehensive research strategy. We also help to develop Alliance Councils' capacity to deliver good growth through best practice case studies, policy discussions, officer-level networks and our program of events bringing the best and latest speakers on growth issues.

Our Alliance

The NGAA is funded by membership fees to represent the interests of our Partner Councils. In recognition of the different stages of growth of eligible Councils, our membership fees are on a sliding scale to be affordable for all Councils regardless of size. you can read our Membership Prospectus here. Our membership categories are:

Partner Councils - Outer Metropolitan Growth Councils whose cities, suburbs and towns are in established, emerging or future population growth areas on the outskirts of capital cities (within metropolitan boundaries). Population growth rates are, have been or are projected to be at least 2% pa.

Supporters - Councils located outside NGAA geographic areas who are also experiencing rapid population growth and wish to participate in research, policy development and professional capacity building.

Partners - organisations with an interest in growth areas, including State and Federal Government and research organisations, and other Local Government groups.

Councillor Matthew Deeth

NGAA Chair, Deputy Mayor, Wollondilly Shire Council

Cr Matthew Deeth has been Chair of the National Growth Areas Alliance since 2019, representing fast-growing local governments in outer metropolitan areas of Australia’s capital cities, where 5.3 million people live.

Matt is the Deputy Mayor at Wollondilly Shire Council in Sydney’s outer south-west. He was first elected to Council in 2016 and served as Mayor in 2018/20. He has lived in Wollondilly all his life and is raising two young children there with his wife.

Matt is passionate about the opportunities offered by fast-growing communities which are too often hampered by incremental, ad-hoc and uncoordinated planning decisions which leave a substantial cost for local government now and into the future.

Matt is proud to take forward policy priorities of NGAA Member Councils from outer urban areas of Perth, Adelaide, Melbourne, Brisbane and Sydney. He believes that as a united collective with a strong voice, backed by sound evidence, shared experiences and expertise, the NGAA is best placed to show how Governments can better invest in and plan thriving and vibrant new communities.
