Night flights at Western Sydney Airport: what the noise complaints mean for new homes

By Nick Henrys, Principal Acoustic Consultant, Resonate Consultants · 13 October 2026 · 5 min read

In late August, ABC News reported that families living close to Western Sydney International were losing sleep to overnight freight flights, a month after the airport opened for freight. The government's noise insulation program had not yet finished work on a single home. This post covers what was reported, how night operations work, and what it means if you're designing or building a home near the airport.

What residents reported

The residents in the ABC story live within about 2 km of the runway, in Luddenham, Greendale, Silverdale, Wallacia, Badgerys Creek and Kemps Creek. They described waking through the night and children falling asleep at school, and one family whose house was built in the early 1950s said they may have to leave. A truck driver living less than 1.5 km from the runway said some nights bring less than two hours of unbroken sleep, which makes it hard to comply with fatigue laws. The residents have invited the Prime Minister and the Transport Minister to spend a night in their homes.

A WSI spokesperson told the ABC that since late July the airport had averaged 11 aircraft a night, or 22 take-offs and landings, four nights a week, Monday to Thursday, between about 8 pm and 5:30 am.

Where the insulation program is up to

The Australian Government's WSI Noise Insulation Program opened for applications in April 2026. It pays for noise treatment of eligible existing homes and community buildings near the airport: acoustic glazing, solid external doors, seals, ceiling insulation and ventilation. Our guide to building near Western Sydney International covers who is eligible and how to apply.

In late August the Department of Infrastructure told the ABC that 236 buildings were eligible, 129 had applied, 74 had been approved, and 17 were having acoustic assessments before work began. No installations had been finished. One resident who applied in May was told their home might not be assessed until April 2027.

Each home needs an on-site acoustic assessment and a noise treatment plan agreed with the owner before work starts, and the works themselves typically take four to six weeks. The program guidelines let the department deal with applications out of order for reasons such as scheduling and the availability of labour and materials. Applications stay open until April 2028.

With flights already running at night, it's easy to understand the residents' frustration. For comparison, in Adelaide, homes along the River Torrens to Darlington (T2D) section of the North-South Corridor are eligible to be considered for similar treatments for road traffic noise. Since late 2025, Resonate have inspected, assessed and issued draft treatment plans for 150+ properties on that project. Obtaining owners' agreement and installing the treatments will take additional time. The Western Sydney program has 236 eligible buildings in total, and it was announced in 2023.

The guidelines cap the works at $250,000 (excluding GST) for a single-storey home and $300,000 for a multi-storey home. That is an upper limit rather than a typical cost, and it covers the assessment, design, approvals, materials and labour.

The program aims to bring the loudest aircraft noise inside bedrooms, living rooms and studies down to 50 dB(A). That is the same level AS 2021, the Australian Standard for building near airports, sets for bedrooms in new homes. The target is non-binding. Where it can't be reached cost-effectively, the program aims for the largest practical reduction.

Night operations

Western Sydney International has no curfew, and it has handled freight flights at night since it opened in late July. A separate change affects Sydney Airport. The Sydney Airport Curfew Act lets a limited number of freight flights and some small aircraft use Sydney Airport during its 11 pm to 6 am curfew, but only until the government gazettes a date from which the Badgerys Creek airport can be used at night. The government set 1 November 2026 as the intended date. From then, those flights can no longer use Sydney Airport during the curfew, and operators either move them to Western Sydney or reschedule them. Traffic will also grow once passenger services start, scheduled from 25 October 2026.

At night, when the wind, weather and traffic allow, the airport uses a mode in which aircraft both arrive from and take off to the south-west. This keeps aircraft away from the more populated suburbs to the north-east. The environmental impact statement found it is likely to increase noise for The Oaks, Warragamba, Silverdale, Cobbitty, Greendale, Hazelbrook and Linden.

The noise maps used for planning, the ANEF and ANEC contours, average aircraft noise over a year and weight night flights more heavily. They don't show how many times a night a house will hear a flyover. The government's Aircraft Overflight Noise Tool gives forecast flight numbers and noise maps for any address, and our guide ANEF vs N70 explains the "number above" maps.

What it means if you're building

The insulation program is for existing buildings. A home is only eligible if it was built before the program started, and a building that had to include noise insulation as a condition of its approval is excluded. If you build a new home near the airport, the acoustic treatment is part of your build and your cost.

Close to the airport, inside the ANEC 20 contour, the state planning rules prevent most new homes. Where one of the exceptions applies, such as a house on a vacant lot or a small granny flat in the ANEC 20–25 band, council has to be satisfied the design meets the AS 2021 indoor levels: 50 dB(A) in bedrooms and 55 dB(A) in living areas. The bedroom level is the one the insulation program is trying to reach in existing houses.

Outside the contour there's usually no aircraft noise requirement, and most of the people who will hear flights at night live outside it. The rooms that matter most are bedrooms. Where the site allows, put them on the side of the house away from the flight path. Acoustic glazing in bedroom windows, solid external doors with seals, an insulated ceiling, and ventilation so the windows can stay shut on warm nights cover most of what the program installs in existing houses. Including them in the design costs less than adding them to a finished house. Our guide to noise attenuation for homes under flight paths goes through each element.
