About the Noise Insulation and Property Acquisition (NIPA) program
The new 24-hour, curfew-free WSI airport will result in aircraft overflight noise to surrounding residents and communities. The NIPA program has been developed by the Australian Government to mitigate aircraft overflight noise to those properties most impacted, within the program eligibility area. It has been informed by feedback gathered through public consultation on the draft EIS. The NIPA program will deliver noise reduction treatments to help reduce aircraft overflight noise experienced inside habitable areas in existing eligible buildings.
The program is expected to commence in late 2025, and continue until the end of 2028. Applications will open shortly after the program commences, and will close approximately nine months prior to end of the program delivery period. Participation in the program is entirely voluntary.
Further information on the NIPA program, including the final eligibility area, will be shown in the program guidelines, to be published online by the end of 2025.
Later in 2025 the department will contact landowners of existing eligible properties located within the eligibility with further information, and invite them to participate in the program.
Further information on the NIPA program is available in the July 2025 brochure.
