Where the noise comes from
Williamstown hears traffic from 2 distinct sources:
Helicopters & other light aircraft

The low layer is rotary and light traffic working the bay and the Point Cook training area — daylight movements along the coastline, separate from the airline stream.
Melbourne Airport (Tullamarine)
live map →4 overflights/day (33%) · typically 3,400 ft
Williamstown catches the runway 34 arrival stream where it crosses the bay — descending traffic on north-flow days at moderate altitude — layered with harbour helicopters and light aircraft along the foreshore.
Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
