Where the noise comes from
Smithfield hears traffic from 3 distinct sources:
Bankstown Airport
live map →6 overflights/day (58%) · typically 1,200 ft

Helicopters & other light aircraft
2 overflights/day (24%) · typically 1,200 ft
Around 2 low overflights a day come from aircraft not operating at a tracked airport — helicopters, seaplanes and light aircraft transiting the area. Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
