New IPC thresholds for state significant development

NSW has changed the rules that determine when the Independent Planning Commission becomes the consent authority for state significant development, with significant implications for renewable energy, resources and standalone battery projects.

The changes are contained in the State Environmental Planning Policy (Planning Systems) Amendment (Independent Planning Commission) 2026, published on 18 August 2026. Some changes took effect immediately, with further changes commencing on 1 November 2026.
