Where the noise comes from
Sydney Kingsford Smith Airport
live map →13 overflights/day (100%) · typically 2,000 ft
Alexandria sits close to the airport's northern side and hears mainly departures — particularly off 34R on north-flow days — climbing past at low altitude as they fan out over the city. Proximity keeps the aircraft low, but the spread of departure tracks means the noise shifts around the suburb rather than following one street line.
