Western Sydney International (Nancy-Bird Walton) Airport (WSI) will have the strictest noise-related land use protections of any airport in Australia.
Good planning and 21st-century technology will limit the noise impact of WSI.
While the airport will result in some increase in noise, steps have already been taken to minimise impacts on the areas surrounding the airport. Long-standing planning restrictions have largely protected the surrounding area from encroaching residential development.
Planning controls are the best way to reduce the impact of noise on the population. By restricting the types of buildings that can be constructed near the airport, the number of people affected will be kept as low as possible.
Current aircraft are much more fuel efficient and quieter than those that preceded them.
Noise from aircraft flying over communities will be a key consideration during the flight path design process. Aircraft noise will also be an area of discussion in the Forum On Western Sydney Airport (FOWSA), the airport's main community engagement forum. As the flight path design process continues, the Government will consider a policy on noise insulation measures.
