Constraint readout
1.28 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Jacana's boundary, with the flood, bushfire and environmental overlays drawn on top. Amber hatching is the published aircraft noise (ANEF) contour. Magenta is where aircraft were observed in the sampled period, brightest below 3,000 ft.

Aircraft noise and flight paths over Jacana
The ANEF contour is a published planning forecast and observed overflight is what a sampled tracking feed recorded - neither describes any individual property.
Inside an aircraft noise contour
81% 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 20 and 25 is conditionally acceptable for houses, usually with noise attenuation built in. The contour is a forecast, not a measurement at any one house.

Observed overflight - sampled 4 Sep to 24 Oct 2026
typical observed square 2 a day
Night movements: observed, lowest 1,000 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.
How this is measured
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.

Jacana planning - frequently asked
Is Jacana flood-prone?
About 20% of Jacana falls within a mapped flood overlay, against the council-wide suburb average of 4%.
Is Jacana bushfire-prone?
Bushfire mapping covers Jacana and little to none of it is mapped as bushfire-prone (the Hume average is 42%).
Is Jacana affected by aircraft noise?
About 81% of Jacana sits inside a published aircraft noise contour, and the highest contour present is ANEF 20 - under AS 2021, land between ANEF 20 and 25 is conditionally acceptable for houses, usually with noise attenuation in the build. ANEF contours are forecasts published per airport and used to control noise-sensitive development; they are not a measurement at any one house, and a property can sit under a flight path and outside every contour.
Is Jacana under a flight path?
Aircraft were observed below 3,000 ft over about 100% of Jacana, in the period sampled (4 Sep 2026 to 24 Oct 2026). The lowest measured aircraft was at 500 ft, with an average of 2,000 ft. At the busiest point in the suburb about 5 aircraft a day were recorded passing over one 500 m square. Traffic is sampled rather than watched continuously and flight paths change with runway use, weather and season; the ANEF contour is the planning instrument.
