Western Sydney International (Nancy-Bird Walton) Airport

Airservices will be conducting testing of the Digital Aerodrome Service (DAS) at and around the new airport site.

A small aircraft will undertake a series of flight validation runs on the following dates:

Thursday 4 June from 3pm until sunset

Friday 5 June from 7am - approximately 9am

During these periods, local residents may notice a small aircraft flying repeated low‑level flight patterns around the airport. These flight patterns are required to support system testing and do not represent the published flight paths for WSI.

Community members can view the aircraft movements via WSI WebTrak page(External link), which also displays the locations of the noise monitors.

The Civil Aviation Safety Authority (CASA) will conduct flight validation of the ILS instrument approach procedures at WSI following successful commissioning of the ILS earlier this month.

Each procedure will be flown once, with the activity expected to be completed within two hours, subject to weather and traffic.

Over the coming weeks, we’ll be out in the community hosting a series of pop‑up stalls to share information about flight paths for Western Sydney International (Nancy‑Bird Walton) Airport, as the airport’s opening gets closer.

These pop‑ups are a chance for locals to drop by, ask questions, and have a chat with members of the project team.

The list of pop‑up stalls below will be updated regularly, so please check back for the latest information.

Webinars

If you can’t make it to a pop‑up stall, or would prefer to join from home, we’re also hosting online information webinars on the following dates:

• Monday 1 June, 6pm–7pm
• Monday 29 June, 6pm–7pm

If you’d like to take part, please register here.

Registered participants will receive an email with a link to join the webinar 24 hours before the session.

Airservices will be conducting testing of the Digital Aerodrome Service (DAS) at and around the new airport site.

A small aircraft will undertake a series of flight validation runs on the following dates:

Wednesday 29 April - Friday 1 May 2026

Monday 4 May - Friday 8 May 2026

Monday 11 May 2026

Thursday 14 May 2026 - Friday 15 May 2026

Flight testing will occur during daylight hours only, most likely in the morning, and is expected to last approximately 2–3 hours on each testing day.

The flights may involve repeated approaches to the runway, as well as landing and departing, as part of the testing process.

During these periods, local residents may notice a small aircraft flying repeated low‑level flight patterns around the airport. These flight patterns are required to support system testing and do not represent the published flight paths for WSI.

Community members can view the aircraft movements via our new WSI WebTrak page, which also displays the locations of the noise monitors.

Update 21 April 2026

To complete testing safely and thoroughly, the testing period has been extended by two additional days.

A small aircraft will conduct a series of flight validation runs on Wednesday 22 April and Thursday 23 April 2026, between 11:00am and 3:00pm.

Airservices is installing two Instrument Landing Systems (ILS) at Western Sydney International Airport.

An ILS is a precision Navigation Landing Aid which provides aircraft with both vertical and lateral guidance when approaching a runway for landing.

Each system must undergo both ground‑based and airborne certification to ensure readiness for operational use by 9 July 2026.

To complete commissioning, a small aircraft will conduct a series of flight validation runs. Details of the flights are:

• Saturday 18 April to Tuesday 21 April 2026
• During daylight hours only
• Each flight is expected to last 4 to 6 hours

Flights may involve repeated approaches to the runway as part of the testing process. Local residents may notice a small aircraft flying repeated low‑level flight patterns around the airport. These flight patterns are required to support system testing and validation.

To ensure safe operations while this aircraft is in the air, the airspace above WSI Airport will be temporarily closed to other aircraft during the above times.

Community members can view the aircraft movements via our new WSI WebTrak page, which also displays the locations of the noise monitors installed last month.

We appreciate the community’s understanding during this essential safety and commissioning activity.

Airservices will be conducting testing of the Digital Aerodrome Service (DAS) at and around the new Western Sydney International Airport site on Thursday 12 February between 11am and 5pm.

Local residents may notice a helicopter flying in a low flight pattern during these times. 

For any questions and concerns, please contact wsia@airservicesaustralia.com

We are pleased to share the Detailed design Feedback Summary and Assessment Report outlining the feedback received from our June - September 2025 engagement and our responses.

Implementation

The Office of Airspace Regulation has approved the Airspace Change Proposal for WSI Airport. The airspace and flight paths will be implemented from 9 July 2026. In the lead up to implementation, we will continue to keep you informed on what to expect and how you can provide feedback on aircraft operations.

Noise monitoring

Prior to the implementation of the airspace and flight paths, we will install noise monitors to record current noise levels and gather data on the new operations. This includes the roll out of the temporary noise monitoring program. Community members will be notified of the outcome of their Expression of Interest submission in the new year. Please refer to the report for further details.

Feedback or enquiries

We will keep the community updated on future opportunities to discuss WSI operations with our team. If you have any questions or feedback in the meantime, please email us at communityengagement@airservicesaustralia.com.

We would like to notify you about upcoming activities this month where you may notice unusual aircraft movement in your area.

CASA validation flights - 23 and 24 October 2025

The Civil Aviation Safety Authority (CASA) is conducting validation flights on Thursday 23 October and Friday 24 October 2025. These validation flights are conducted as part of the Airspace Change Proposal (ACP) process and aim to confirm that procedures for Western Sydney International (WSI) Airport can be safely flown and that the airspace is clear of obstructions.

You may notice a small propeller-driven aircraft flying as low as several hundred feet at times and an uncommon flying pattern. This is to make sure obstacles are accurately marked on charts and no new obstacles exist. Obstacles can be towers, trees, masts or buildings that can be a danger to aircraft.

If you wish to find out more about the validation activities, please contact CASA on 131 757 or submit your enquiry through CASA’s website.

Emergency Exercise at WSI Airport – 28 & 29 October 2025

The WSI Airport operator, in partnership with the NSW Rural Fire Service (RFS), will conduct an emergency exercise at WSI Airport on Tuesday 28 October and Wednesday 29 October 2025.

On Tuesday 28 October, RFS will operate a Boeing 737 aircraft, flying from Richmond RAAF Base to WSI Airport. The aircraft is scheduled to:

• arrive at WSI Airport between 8:00am and 9:30am
• depart WSI Airport between 2:00pm and 3:30pm

During these times, you may notice the aircraft flying at low altitude between Richmond and WSI Airport. It will be operating in Class G airspace, below 5,000 feet.

Please note that the aircraft will not fly any of the proposed WSI flight paths, as these are still pending validation by CASA

To ensure safe operations while this aircraft is in the air, the airspace above WSI Airport will be temporarily closed to other aircraft during the above times.

If you wish to find out more about the emergency exercise, please contact the team at Western Sydney International Airport directly on 1800 972 972 or info@wsiairport.com.au

Community engagement on flight path and airspace changes for Western Sydney International (Nancy-Bird Walton) Airport (WSI) has now concluded. We would like to thank everyone who provided feedback and submitted an expression of interest or location suggestion for a temporary noise monitor.

Relevant feedback from the community regarding Noise Abatement Procedures (NAPs) will be reviewed and considered in further development of WSI NAPs.

The expressions of interest and location suggestions received for the temporary noise monitors will be reviewed and a shortlist of appropriate locations identified for inclusion in this program. You will be notified of the outcome of your submission shortly and suitable candidates will be advised of next steps.

Subject to CASA approvals, the airspace changes will be implemented in mid-2026 ahead of the opening of WSI Airport. We will keep the community updated on progress and future opportunities to discuss WSI operations with our team.
