The Assessment Framework is changing in line with amendments to the Infrastructure Australia Act 2008. Find out more here.   

During Stage 3 of Infrastructure Australia’s assessment process, you will undertake a detailed assessment of options that respond to problems and opportunities identified in Stage 1 and Stage 2. You will document these outcomes in a business case. 

When you submit your business case to us, we will assess your detailed options analysis process, the merit of your preferred option and the deliverability considerations of the proposal.

This document outlines tools and methodologies that can help you with this process and provides links to supporting technical guides.
