About NGAA

More than 20 of the fastest growing councils around Australia are members of the National Growth Areas Alliance (NGAA). NGAA areas are growing at double the national rate. Collectively, Australia’s outer suburbs are currently home to five million people – and counting! In just 15 years, another 2.5 million people will call these areas home.

As the peak advocacy group for outer suburbs – from Penrith in Sydney’s west to Wanneroo in Perth’s north – the Alliance works with its members to advocate to state and federal governments for a fair go for outer suburbs. In addition to highlighting the challenges – and opportunities – presented by such growth, the Alliance also works with industry and other stakeholders to advocate for residents to get the infrastructure and services they need and deserve.
