The 2019 Audit was Infrastructure Australia's second national Audit. It examined the major challenges and opportunities facing Australia's infrastructure over the next 15 years.
The 2019 Audit covered five infrastructure sectors: transport, energy, water, telecommunications and digital, and - for the first time - social infrastructure. Across these sectors 180 challenges and opportunities were identified.
It stated that Australia faces an 'unprecedented period of uncertainty'.
The compounding issues of a changing climate, global economic trends and political polarisation were some of the uncertainties it highlighted.
The 2019 Audit has played a fundamental role in informing our recommendations for the Infrastructure Priority List and is the primary evidence base for the 2021 Plan.
