Old Grafton Gaol Redevelopment Cost Benefit Economic Analysis (CBA) 

The Challenge

In 2019, the Old Grafton Gaol ceased operations, prompting the Grafton Ngerrie Local Aboriginal Land Council (GNLALC) to commence a land rights claim over the site. This agreement resulted in the transfer of ownership of one of the Old Grafton Gaol sites to GNLALC, formalised on 1 March 2024. However, the site is unusable and does not benefit the local community, prompting GNLALC to seek investment funds for development.

To seek funding, the GNLALC required a business case requesting funding to develop the precinct.

The Action

Polis Partners supports GNLALC’s funding bid by preparing an economic report and cost-benefit model for the Old Grafton Gaol precinct. They consolidate existing business case materials, identify potential social and economic benefits, and quantify impacts using government-aligned modelling. The final report outlines the project rationale, methodology, and projected outcomes to strengthen the case for investment.

The Results

The analysis highlights over ten benefit types—including employment, tourism, commercial activity, and improved social cohesion —benchmarked against capital and operating costs. These findings are embedded in GNLALC’s business case, now submitted to government to secure funding for precinct development.
