Aircraft noise and flight paths over Tweed Heads South
Two different things, kept apart on purpose. The ANEF contour is the planning instrument - a forecast published per airport that planning schemes use to control noise-sensitive development. Observed overflight is what a sampled aircraft-tracking feed actually recorded over the suburb - where aircraft flew, how low and how often.
Inside an aircraft noise contour
27% of the suburb's land sits inside a published ANEF or airport-environs contour. Contours vary street by street, so whether a particular lot is inside one needs a property-level check.
Highest contour present
Under AS 2021, land between ANEF 25 and 30 is generally unacceptable for new houses; 20 to 25 is conditionally acceptable with noise attenuation. The contour is a forecast, not a measurement at any one house.

Observed overflight - sampled 4 Sep to 2 Oct 2026
typical observed square 2 a day
Night movements: observed, lowest 500 ft - night is sampled as often as day, but night traffic is light, so this is a floor and no rate can be put on it.
Traffic is sampled rather than watched continuously, so every figure is a floor: aircraft not captured between samples are not represented. Rates are per 500 m square - the busiest square in the suburb, not a count of flights over the suburb - and a square is only rated where enough traffic was seen to measure it. Altitudes are above mean sea level. Flight paths change with runway use, weather, season and airspace design. This is a record of observed traffic; it is not a noise contour and not a planning control.
