With passenger flights at Western Sydney International Airport beginning on Sunday, October 25, Hawkesbury residents have another way to explore what aircraft noise could sound like at their homes.
A free website, Flight Path Australia, translates estimated aircraft noise into five descriptions: Quiet, Faint, Noticeable, Loud and Very loud.
Its creator, prospective home buyer Sam Morison, says the project began with a practical question he struggled to answer while searching for a property.
“I couldn't find out what the planes sound like on a particular street,” Mr Morison said.
“So I built a free map that works it out for any street in the eight capital cities.”
Western Sydney International’s first commercial passenger departure is scheduled for 11am on Sunday, with a Jetstar Airbus A320 service to the Gold Coast.
For Hawkesbury households, the new map offers a starting point for checking individual addresses and comparing estimated noise under existing and future flight paths.
Mr Morison says his analysis identifies 58 Sydney suburbs, home to about 359,000 people, where the map’s noise category increases with Western Sydney International’s flight paths included.
Among his examples, Wallacia moves from Quiet to Loud and Luddenham from Faint to Loud. St Clair, St Marys and Kingswood move from Faint to Noticeable.
Those figures are the developer’s estimates. They do not establish that every household in those suburbs will experience the same change, or that the predicted conditions will occur on opening day.
The website’s published methodology says its Western Sydney calculations use the Australian Government’s official flight paths and aircraft heights, combined with aircraft noise data. Its categories describe the estimated outdoor peak noise from a single aircraft passing, rather than an average across the day.
That distinction matters: how loud an individual aircraft sounds and how often aircraft pass overhead are different questions.
The developer also acknowledges that the map provides modelling rather than measurements. Weather, runway use, aircraft type and variations in flight tracks can change what residents actually hear.
There is a further limitation relevant to Hawkesbury readers: military aircraft noise is excluded from its ratings. The map therefore does not provide a complete picture of aircraft noise around RAAF Base Richmond.
Residents can compare its estimates with the Government’s Aircraft Overflight Noise Tool. Airservices Australia also provides WebTrak, which displays flight activity and recordings from noise monitors around Western Sydney and the Blue Mountains.
For residents and prospective buyers, checking an individual address offers more useful detail than assuming an entire suburb will have the same experience.
