Where the noise comes from
Mosman hears traffic from 2 distinct sources:
Sydney Kingsford Smith Airport
live map →15 overflights/day (93%) · typically 5,700 ft
Mosman's fixed-wing traffic passes high — arrivals tracking across the lower north shore at altitude on their way into the approach sequence, audible on still days but rarely intrusive.
Helicopters & other light aircraft
1 overflights/day (7%) · typically 800 ft
The lower, more noticeable visitors are rotary and light aircraft: helicopters working the harbour and seaplanes tracking to and from Rose Bay pass the Mosman peninsula low over the water. They are infrequent, daylight-only, and concentrated on weekends and fine weather.
Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
