Infrastructure Australia is an independent statutory body that evaluates proposals for nationally significant infrastructure, prioritises infrastructure investments, and provides advice to Australian governments and industry on the infrastructure needs of the country to support economic growth, productivity, and liveability. The Infrastructure Priority List, published and updated regularly by Infrastructure Australia, sets out the investments that the organisation has assessed as nationally significant and ready for investment, organised into categories reflecting their level of project development from early-stage proposals through to projects with a completed and approved business case ready for procurement. Project evaluation methodology developed by Infrastructure Australia provides a consistent framework for assessing the costs and benefits of proposed infrastructure investments, ensuring that public funding is directed to projects that generate net economic and social benefits and that the assessment of competing proposals is transparent and comparable. The methodology draws on established cost-benefit analysis techniques adapted for the specific characteristics of infrastructure investment, including the long asset lives, significant upfront capital costs, and complex interactions between different infrastructure systems that characterise major transport, water, energy, and communications projects. Infrastructure Australia works with Commonwealth, state, and territory governments and with project proponents to improve the quality of infrastructure business cases, providing feedback on early-stage proposals and guidance on how to strengthen the analysis and evidence base before a proposal is submitted for formal assessment. The organisation also publishes research and analysis on broader infrastructure system issues, including assessments of urban infrastructure needs, the impact of population growth on transport and utilities capacity, and the reform agenda required to improve the efficiency and sustainability of infrastructure delivery and operation across Australia. International engagement with comparable infrastructure bodies in other countries contributes to the development of best practice in infrastructure evaluation and planning methodology.
