Constraint readout
2.92 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Leichhardt'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.

How common is mapped flood risk across Leichhardt properties?
Counts of properties, not share of land, across 1,837 analysed Leichhardt properties; no individual property result is identified.

From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Leichhardt.
Has Leichhardt flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Leichhardt: 173 of the 1,837 properties we analysed (9.4%) sit at least partly inside a mapped historical flood extent (Historic Flood 1974: 173, Historic Flood 2011: 53). The free address check says whether a given lot is inside one.

Aircraft noise and flight paths over Leichhardt
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
100% 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 at ANEF 30 and above is generally unacceptable for new houses and most noise-sensitive uses. The contour is a forecast, not a measurement at any one house.

Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 1 a day
Night movements: not established - night is sampled as often as day, but too few night flights have been seen here to conclude either way.
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.

Leichhardt planning - frequently asked
Is Leichhardt flood-prone?
About 60% of Leichhardt falls within a mapped flood overlay, against the council-wide suburb average of 46%. Across the suburb, 43% of the 1,837 properties we analysed carry some level of mapped flood risk, including 121 rated high risk or historically affected. Published flood models are held over parts of Leichhardt; the free check on the Flood Model Report page says whether one reaches a given address.
Has Leichhardt flooded?
Yes. Recorded flood mapping reaches into Leichhardt: 173 of the 1,837 properties we analysed (9.4%) sit at least partly inside a mapped historical flood extent (Historic Flood 1974: 173, Historic Flood 2011: 53). The free address check says whether a given lot is inside one.
Is Leichhardt bushfire-prone?
Around 25% of Leichhardt is mapped as bushfire-prone, compared with a Ipswich City average of 50%.
Is Leichhardt affected by aircraft noise?
About 100% of Leichhardt sits inside a published aircraft noise contour, and the highest contour present is ANEF 30 - under AS 2021, land above ANEF 25 is generally considered unacceptable for new houses, and 20-25 conditionally acceptable with noise attenuation. 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 Leichhardt under a flight path?
Aircraft were observed below 3,000 ft over about 100% of Leichhardt, in the period sampled (4 Sep 2026 to 7 Nov 2026). The lowest measured aircraft was at 500 ft, with an average of 2,000 ft. At the busiest point in the suburb about 3 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.
