A planning-constraint profile of Walloon
(Ipswich City, QLD) - 18.88 km², mapped from live council and
state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
18.88 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Walloon'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 Walloon properties?
Counts of properties, not share of land, across 1,525 analysed Walloon properties; no individual property result is identified.
Lot-level readout
Flood-risk rating across all 1,525 properties
From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Walloon.
Has Walloon flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Walloon: 80 of the 1,525 properties we analysed (5.2%) sit at least partly inside a mapped historical flood extent (Historic Flood 2011: 80). The free address check says whether a given lot is inside one.
Suburb-wide totals across 1,525 analysed properties; they do not identify or describe any individual property.
Recorded historical flood mapping
80 analysed properties intersect at least one mapped historical event extent.

Aircraft noise and flight paths over Walloon
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
72% 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 2,000 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.

Walloon planning - frequently asked
Is Walloon flood-prone?
About 45% of Walloon falls within a mapped flood overlay, against the council-wide suburb average of 46%. Across the suburb, 54% of the 1,525 properties we analysed carry some level of mapped flood risk, including 261 rated high risk or historically affected. Published flood models are held over parts of Walloon; the free check on the Flood Model Report page says whether one reaches a given address.
Has Walloon flooded?
Yes. Recorded flood mapping reaches into Walloon: 80 of the 1,525 properties we analysed (5.2%) sit at least partly inside a mapped historical flood extent (Historic Flood 2011: 80). The free address check says whether a given lot is inside one.
Is Walloon bushfire-prone?
Around 67% of Walloon is mapped as bushfire-prone, compared with a Ipswich City average of 50%.
Is Walloon affected by aircraft noise?
About 72% of Walloon 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 Walloon under a flight path?
Aircraft were observed below 3,000 ft over about 95% of Walloon, and over about 98% 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 2,000 ft. At the busiest point in the suburb about 8 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.
