We are reviewing our methodology for calculating the discount rate for local government infrastructure contributions.
We published our Issues Paper in September 2025 and consulted with stakeholders during September and October 2025. The submissions we received are now published on our website.
We help a public workshop on 14 October 2025. The presentation and a recording of the workshop are available here.
We anticipate releasing and consulting on our Draft Report in early 2026.
We use our methodology to calculate the discount rate that we recommend councils apply if they are using a net present value approach to calculate local infrastructure contributions. IPART calculates and publishes the discount rate every 6 months.
This review aims to ensure that our discount rate methodology is fit for purpose and consistent with the aim of timely provision of local infrastructure.
This review affects:
- local councils
- property developers.
