state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
3.83 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Cannon Hill'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.

Has Cannon Hill flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Cannon Hill: 72 of the 3,422 properties we analysed (2.1%) sit at least partly inside a mapped historical flood extent (February 2022: 71, Historic Flood 1974: 22, January 2011: 13). The free address check says whether a given lot is inside one.

Aircraft noise and flight paths over Cannon Hill
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
2% 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.
Contours held
- Brisbane City Plan Airport Environs ANEF
Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 9 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.

Cannon Hill planning - frequently asked
Is Cannon Hill flood-prone?
About 36% of Cannon Hill falls within a mapped flood overlay, against the council-wide suburb average of 31%. Across the suburb, 6% of the 3,422 properties we analysed carry some level of mapped flood risk, including 99 rated high risk or historically affected. Modelled flood depth, velocity and flood level are held for about 3,400 Cannon Hill addresses, from published flood studies; the free check on the Flood Model Report page says whether a model reaches a given address.
Has Cannon Hill flooded?
Yes. Recorded flood mapping reaches into Cannon Hill: 72 of the 3,422 properties we analysed (2.1%) sit at least partly inside a mapped historical flood extent (February 2022: 71, Historic Flood 1974: 22, January 2011: 13). The free address check says whether a given lot is inside one.
Is Cannon Hill bushfire-prone?
Around 24% of Cannon Hill is mapped as bushfire-prone, compared with a Brisbane City average of 27%.
Is Cannon Hill affected by aircraft noise?

The lowest measured aircraft was at 1,000 ft, with an average of 1,500 ft. At the busiest point in the suburb about 96 aircraft a day were recorded passing over one 500 m square.
