state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
10.8 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Karrabin'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 Karrabin properties?
Counts of properties, not share of land, across 199 analysed Karrabin properties; no individual property result is identified.
Lot-level readout
Flood-risk rating across all 199 properties
From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Karrabin.
Has Karrabin flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Karrabin: 45 of the 199 properties we analysed (22.6%) sit at least partly inside a mapped historical flood extent (Historic Flood 2011: 36, Historic Flood 1974: 27). The free address check says whether a given lot is inside one.
Suburb-wide totals across 199 analysed properties; they do not identify or describe any individual property.
Recorded historical flood mapping
45 analysed properties intersect at least one mapped historical event extent.

Aircraft noise and flight paths over Karrabin
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.
Contours held
- Defence Airfields ANEF
- Ipswich City Council ANEF
Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 1 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.
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.

Karrabin planning - frequently asked
Is Karrabin flood-prone?
About 44% of Karrabin falls within a mapped flood overlay, against the council-wide suburb average of 46%. Across the suburb, 56% of the 199 properties we analysed carry some level of mapped flood risk, including 58 rated high risk or historically affected. Published flood models are held over parts of Karrabin; the free check on the Flood Model Report page says whether one reaches a given address.
Has Karrabin flooded?
Yes. Recorded flood mapping reaches into Karrabin: 45 of the 199 properties we analysed (22.6%) sit at least partly inside a mapped historical flood extent (Historic Flood 2011: 36, Historic Flood 1974: 27). The free address check says whether a given lot is inside one.
Is Karrabin bushfire-prone?
Around 91% of Karrabin is mapped as bushfire-prone, compared with a Ipswich City average of 50%.
Is Karrabin affected by aircraft noise?
About 100% of Karrabin sits inside a published aircraft noise contour, and the highest contour present is ANEF 35 - 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 Karrabin under a flight path?
Aircraft were observed below 3,000 ft over about 89% of Karrabin, and over about 94% at any altitude up to 10,000 ft, in the period sampled (4 Sep 2026 to 7 Nov 2026). The lowest measured aircraft was at 500 ft, with an average of 1,500 ft. At the busiest point in the suburb about 28 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.
