Previous Infrastructure Australia research and the 2019 Audit highlight the disparities of infrastructure provision in the outer suburbs of Australia's Fast-growing Cities. These suburbs can be significantly disadvantaged, particularly when it comes to public transport access.48
Whether they are brand new suburbs or substantially densified existing suburbs, disparate forms of development yield different experiences for residents. The significant governance challenges in managing such a wide range of developments, and community reactions to it, do not allow for a one-size-fits all approach. However, it is possible to apply general principles to meet a specific challenge or need.
If they are to thrive, outer suburbs must be supported by appropriate infrastructure that is delivered in alignment with development.
For example, transport agencies must routinely think beyond standard routes that link suburbs with CBDs areas to non-radial connections between outer urban agglomerations. These should match how people in these suburbs move around, helping cities to function efficiently.
" If they are to thrive, outer suburbs must be supported by appropriate infrastructure that is delivered in alignment with development. "
This approach requires 'joined-up' planning and delivery across multiple levels of government so it considers the needs of all stakeholders.
Earlier Infrastructure Australia reform recommendations remain relevant today, including:49
• establishing better strategic planning processes that align with future population growth
• ensuring that in high-growth areas, the full range of economic and social infrastructure is planned and delivered in a place-centric manner
• implementing governance arrangements that translate strategic plans into tangible local outcomes through appropriate funding, resourcing and accountability and that better engage communities
• enhancing incentives for improved governance and better collaboration between levels of government, including local and state infrastructure funding mechanisms
• making better use of existing assets, including promoting shared-use arrangements, non-capital delivery options, addressing maintenance backlogs and better use of technology.
Improving asset and network quality, timeliness, capacity and use will result in optimised infrastructure use and better investment decisions for new infrastructure.
