The Airport

    Why do we need a second airport?

    Demand for aviation services in the Sydney region is forecast to double from 2015 to 2035. Even if operational restrictions were removed at Sydney (Kingsford Smith) Airport, it could not meet Sydney’s long term aviation needs (Department of Infrastructure and Transport, 2012).

    There is expected to be an increase in the demand for aviation services to meet the needs of population growth, as well as the growth in business activities, generally within the Sydney Basin. There are several key industries in the area that depend on air transport services.

    The physical constraints at Sydney (Kingsford Smith) Airport limit its ability to handle further passenger growth. The size of the airport site limits the ability to deliver any significant upgrade or reconfiguration of the runways, taxiways and apron systems that would be required to respond to aviation demand.

    What is the airport’s capacity?

    The single runway at WSI will be capable of handling up to 10 million annual passengers and around 81,000 air traffic movements by 2033 including freight operations. It is expected that by 2033 there will be a total of 222 flights per day (88 per cent passenger, 12 per cent freight).

    Why is there no curfew for WSI?

    WSI has always been planned and approved to operate on a 24/7 curfew-free basis. Operating without a curfew will boost the airport’s ability to create more jobs in Western Sydney and meet the demand for aviation services in the region.

    Curfews are federally legislated instruments administered by the Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts, and Airservices Australia has no power under the Air Services Act 1995 to pursue curfews.

WSI flight paths

    How were flight path locations determined?

    The airspace and flight path design process for WSI has sought to optimise flight paths based on safety, efficiency, capacity, and noise and environmental considerations, while minimising changes to existing airspace arrangements in the Sydney Basin to the greatest

    extent practical.

    Any necessary changes and associated impacts to the flight paths at other airports to accommodate aircraft operations from WSI have been considered in terms of safety, national security (Department of Defence), efficiency, equity of airspace access, existing aircraft operating standards and environmental impact.

    The flight path design follows international best practice and meets a set of 12 Airspace Design Principles set out in the Western Sydney Airport Plan.

    These principles include minimising:

    • aircraft overflight and noise impacts on residential areas, to the maximum extent possible
    • the impact of night-time operations on communities
    • the impacts of aircraft operations on natural and visually sensitive areas, including the Blue Mountains.

    There are four main phases to the airspace and flight path design process:

    1. Planning
    2. Preliminary design and environment assessment
    3. Detailed design
    4. Implementation.

    It is an iterative process informed by community and stakeholder engagement at each phase.

    Further information on the airspace and flight path design process is provided in Chapter 6 and 7 in the EIS.

    The Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts has overall responsibility for the development of the Environmental Impact Statement (EIS) for the preliminary flight paths.

    The Minister for Infrastructure, Transport, Regional Development and Local Government, in consultation with the Minister for Environment, authorised the flight paths for WSI as presented in the final EIS in June 2025.

    Airservices Australia is responsible for detailed design and implementation of the airspace and flight paths for WSI.

    What is the purpose of the detailed design phase?

    Detailed design involves further refining the flight paths through simulation testing and ongoing safety assessments ahead of implementation. Changes to the flight paths’ location or planned operation will only be made if a safety issue is identified.

    Throughout detailed design we will be actively engaging with industry stakeholders and communities across Greater Sydney and the Blue Mountains to ensure awareness of the location of the flights paths, how they will operate, and what communities can expect from these operations.

    Subject to approval by the Civil Aviation Safety Authority (CASA), the flight paths will be implemented in mid-2026 ahead of the airport’s opening in 2026.

    Will night-time operations be different to daytime operations?

    Yes, flight paths at night take advantage of the additional airspace capacity due to the curfew for Sydney (Kingsford Smith) Airport.

    At night (11pm to 5.30am) when air traffic demand is lower and weather conditions permit (calm wind conditions with no rain), Reciprocal Runway Operations (RRO) can be used to minimise aircraft noise over the most heavily populated areas north-east of WSI.

    What is Reciprocal Runway Operations (RRO) mode?

    In RRO mode, aircraft take off and land from the same direction. At WSI, aircraft take off to the south-west, while they land from the south-west. RRO at WSI can only be used between 11pm and 5.30am and is subject to various factors including suitable air traffic volumes and weather conditions.

    Will there be impacts to the flight paths and operations of other airports in Sydney?

    Some flight paths and operating procedures servicing other airports in the Sydney region need to be altered to facilitate WSI flight paths into this already busy and complex airspace. This includes changes to flight paths servicing Sydney (Kingsford-Smith) and Bankstown airports, and new approach procedures into Camden Airport. The Royal Australian Airforce (RAAF) Base Richmond will also require changes to an arrival path and its approach procedures.

    For more information, refer to Chapter 8 and 21 of the EIS.

    What impacts will the flight paths have on rainwater tank storage?

    The EIS found that the emissions to air derived from the operation of aircraft would have a negligible to low impact on water quality in rainwater tanks in the community. Potential impacts on these water supplies would be so low they would not be measurable. An assessment of air and water quality impacts is included in Chapter 12 of the EIS and Technical Paper 2.

    How will operations at WSI affect emergency services operations?

    Emergency services operations are usually conducted at short notice and can occur at any time of the day or night.

    Emergency services operations take priority over other aircraft.

    Aircraft in the vicinity may also be asked to hold their current position by circling in the air to allow the emergency services aircraft to quickly land or depart before them.

    How does fuel dumping work?

    Fuel jettisoning (also known as fuel dumping) is only required in extremely rare circumstances in the event of an emergency and is only possible in certain types of aircraft.

    In the event that fuel jettisoning is required, the Civil Aviation Safety Authority (CASA) and Airservices enforce strict procedures on when and where it can occur.

    Jettisoned fuel vaporises rapidly and disperses widely. Fuel jettisoning generally results in no impacts at ground level.

Noise

    What are Noise Abatement Procedures (NAP)?

    Every major airport has NAPs, which are procedures designed to reduce the impact of aircraft noise on the community.

    Communities near airports may be sensitive to operations at different times of the day and night. NAPs are implemented by Air Traffic Control (ATC), airports or airport owners. They contain instructions for pilots and ATC for the runways and flight paths, as well as procedures that should be followed to minimise the impacts of aircraft overflight noise on the community.

    Where can I find the Government’s noise insulation and property acquisition policy?

    Noise insultation and property acquisition is outside of Airservices’ remit and is managed by the Department of Infrastructure, Transport, Regional Development, Communications, Sport and The Arts. Please contact the Department at: wsiflightpaths@infrastructure.gov.au

    What opportunities will be available to provide feedback during the detailed design phase?

    There will be several opportunities to provide feedback during the detailed design phase on the proposed Noise Abatement Procedures and noise monitoring program.

    This will include targeted community engagement sessions and stakeholder briefings. Community consultation will be held across Greater Sydney, including the Blue Mountains.

    Feedback is not being sought on the new flight paths as these have already been authorised by government, but we will be seeking feedback to ensure awareness of these flight paths and to answer any questions about their operation.
