About the program

The WSI Noise Insulation Program delivers noise treatment works to existing eligible buildings to help reduce aircraft noise inside homes and other noise‑sensitive spaces.

Why the program is being delivered

Western Sydney International Airport will operate as a 24‑hour, curfew‑free airport. While the airport will bring employment and business opportunities to the region, aircraft overflight noise will be experienced by surrounding residents and communities.

The Noise Insulation Program is one of the measures used by the Australian Government to help address these noise impacts.

Participation in the program is voluntary.

 

How the program was developed

The program is based on the Noise Insulation and Property Acquisition policy, which was released for public consultation in October 2023 as part of the draft WSI airspace and flight path design Environmental Impact Statement (EIS).

Following community and stakeholder feedback, the policy was finalised in late 2024 and used to design and develop the Noise Insulation Program.

The detailed rules for the program, including the eligibility area and how the program is delivered, are set out in the Program Guidelines.

 

Who is delivering the program

The Noise Insulation Program is delivered by the Australian Government through the Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts.

A managing contractor has been appointed to work directly with landowners and residents to:

  • provide information about the program
  • arrange property and noise assessments
  • manage the delivery of approved noise treatment works

All works are delivered in accordance with relevant laws, building requirements and safety standards.

 

What noise treatments may be offered

Eligible buildings are assessed by specialist acoustic and building advisers to identify practical and cost‑effective noise treatment solutions suited to each building.

Depending on the building and its condition, noise treatment works may include:

  • sealing gaps around doors and windows
  • upgrading windows or external doors
  • installing acoustic insulation in ceilings or roof spaces
  • improving the performance of poor performing existing skylights
  • enclosing open eaves
  • installing or upgrading ventilation or air‑conditioning systems so windows can remain closed

Landowners will be invited to review and provide input into the Noise Treatment Plan developed for their property before any works begin.

 

Is there a cost?

No. The Australian Government covers the cost of agreed noise treatment works delivered under the program.

Landowners do not receive funding directly and are not required to arrange quotes or contractors themselves.

 

How long will the program run

The Noise Insulation Program opened for applications in April 2026.

The program will run for three years, with applications open for two years, through to April 2028.
 

Taking part in the program is voluntary. In summary, the process involves:

  1. 1. Apply

    Landowners choose whether to apply for an eligible property during the application period.

  2. 2. Application assessment

    Applications are assessed against the Program Guidelines, and the outcome is provided in writing.

  3. 3. Property assessment and Noise Treatment Plan

    Approved properties are inspected by acoustic and building specialists and a tailored Noise Treatment Plan is developed. Landowners can review and provide input before the plan is finalised.

  4. 4. Agreement and scheduling

    Landowners enter into a formal agreement for the approved works, which are then scheduled in consultation with residents.

  5. 5. Works and completion

    Approved works are delivered, followed by inspections and final assessments to confirm required standards are met.
