Business case and economic modelling for a $46m infrastructure upgrade to Perth's Kwinana Freeway.
Aaron was engaged by Main Roads WA to develop a business case and provide economic and financial modelling for a $46m infrastructure upgrade to Perth's Kwinana Freeway. These upgrades included strengthening the seawall of the freeway and demonstrating expected safety improvements and congestion alleviation from reduced road inundation events.
Central Arnhem Road Upgrades
Infrastructure NT · Darwin, NT
Business case for a $355m long-term road upgrade program for a 645km stretch connecting Nhulunbuy with the Stuart Highway.
Aaron developed the business case for a $355m long-term road upgrade program for Central Arnhem Road, a 645 kilometre stretch connecting the remote community of Nhulunbuy with the Stuart Highway.

Port Adelaide Infrastructure Upgrade Program Prioritisation
Department for Infrastructure and Transport · Adelaide, SA
Prioritisation of over twenty competing infrastructure upgrades in the Port Adelaide area.
Aaron was tasked with conducting a detailed prioritisation of over twenty competing infrastructure upgrades in the Port Adelaide area, each with different objectives and challenges. Aaron conducted a rapid cost-benefit analysis for each project and provided impact-based recommendations.

Education


Reschematic
When I started my career ten years ago I wondered: why don’t we have any software to help us with economic modelling? As recently as two years ago, I was still wondering the same thing.
In response to this I built Reschematic to make project evaluation not only easier, but more accessible. It’s a project screening tool that leverages AI to build CBA and ROI models. Local governments and not-for-profits find it particularly useful in helping them to move faster, present interactive business cases, and showcase the initiatives that deserve attention.
My experience building Reschematic has deepened the way that I think about the intersection of economics, technology, and decision-making. I think that in the years ahead, as AI becomes more ubiquitous, economists will need to increasingly engage with the technology to support the delivery of trusted advice, shifting their focus from building models by hand to defining the assumptions, structure, and judgement that guide decisions towards outcomes that genuinely improve the world we live in.
