Bankstown Airport
live map →5 overflights/day (55%) · typically 1,200 ft

Around 3 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.
