Infrastructure is about meeting the challenges of the present and the future. This requires cooperation between governments, investors, industry and the community. That's why the nation's independent infrastructure advisor, Infrastructure Australia, has defined its priority projects and initiatives. The Infrastructure Priority List is the authoritative list of nationally significant infrastructure investments that Australian needs over the next 15 years. It provides independent evidence-based advice to governments and industry and guides decision-making on how best to allocate resources. The list uses the Australian Infrastructure Audit as the primary evidence base. From there, Infrastructure Australia did a detailed assessment of the infrastructure gaps and requirements right across the country and consulted closely with federal and state and territory governments to reach consensus. The priority list is a living document that evolves over time to meet emerging challenges and opportunities. It's regularly reviewed and updated by the Infrastructure Australia Board as new business cases and proposals come through. There are two broad groupings in the list, projects and initiatives. Projects are advanced proposals that have undergone a full business case assessment by Infrastructure Australia. They'll remain on the list until construction or delivery begins. The other category is initiatives. These are proposals assessed and endorsed by the Infrastructure Australia Board that address a nationally significant problem but need further development into a full business case. Initiatives or projects that address particularly significant problems or opportunities are highlighted as high priority. Ultimately, the priority list supports transparent evidence base decision-making. So governments can select the projects that deliver the most community benefit and deliver a better infrastructure future for all Australians.
