The reforms are designed to increase housing supply and provide more affordable living options for Western Sydney families.
The changes reverse previous restrictions on secondary dwellings in parts of the Western Parkland City and will apply to land located within the Australian Noise Exposure Concept (ANEC) 20-25 contour.
These areas are expected to experience lower levels of aircraft noise once the airport becomes operational. The ANEC is a long-term planning tool used to forecast aircraft noise impacts around the new airport under various future operational
scenarios, including the possible addition of a second runway.
Under the reforms, eligible homeowners in the local government areas of Wollondilly, Camden, Fairfield, Liverpool and Penrith will be able to build secondary dwellings of up to 85 square metres.
These dwellings must include aircraft noise reduction measures such as double-glazed windows to improve liveability for residents.
The Government says the reforms are designed to strike a balance between protecting the long-term operation of Sydney’s first curfew-free airport and supporting growing communities in one of Australia’s fastest-growing regions.
The changes are expected to help families remain close together, support multi-generational living and provide greater housing flexibility near emerging employment hubs linked to the airport and the broader Aerotropolis development.
Secondary dwellings will not be permitted in areas forecast to experience higher levels of aircraft noise.
Deputy Premier and Minister for Western Sydney Prue Car said the reforms would help local families benefit from the jobs, investment and opportunities being created through the airport project.
She said the changes reflected the government’s focus on practical housing reforms while supporting the long-term success of Western Sydney.
Minister for Planning and Public Spaces Paul Scully said the government was continuing to use every available planning tool to increase housing supply and create more affordable and flexible living options close to jobs, transport and family support networks.
Member for Wollondilly Judy Hannan welcomed the reforms, saying local residents had consistently called for greater housing flexibility to support children, parents and extended families living close to home.
