A planning-constraint profile of Peak Crossing
(Scenic Rim Regional, QLD) - 56.37 km², mapped from live council and
state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
56.37 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Peak Crossing'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 Peak Crossing properties?
Counts of properties, not share of land, across 421 analysed Peak Crossing properties; no individual property result is identified.
Lot-level readout
Flood-risk rating across all 421 properties
From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Peak Crossing.
Has Peak Crossing flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Peak Crossing: 81 of the 421 properties we analysed (19.2%) sit at least partly inside a mapped historical flood extent (Defined Flood Event: 81). The free address check says whether a given lot is inside one.
Suburb-wide totals across 421 analysed properties; they do not identify or describe any individual property.
Recorded historical flood mapping
81 analysed properties intersect at least one mapped historical event extent.

Aircraft noise and flight paths over Peak Crossing
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.

Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 1 a day
Night movements: observed, lowest 5,000 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.

Peak Crossing planning - frequently asked
Is Peak Crossing flood-prone?
About 13% of Peak Crossing falls within a mapped flood overlay, against the council-wide suburb average of 14%. Across the suburb, 19% of the 421 properties we analysed carry some level of mapped flood risk, including 56 rated high risk or historically affected. Published flood models are held over parts of Peak Crossing; the free check on the Flood Model Report page says whether one reaches a given address.
Has Peak Crossing flooded?
Yes. Recorded flood mapping reaches into Peak Crossing: 81 of the 421 properties we analysed (19.2%) sit at least partly inside a mapped historical flood extent (Defined Flood Event: 81). The free address check says whether a given lot is inside one.
Is Peak Crossing bushfire-prone?
Around 42% of Peak Crossing is mapped as bushfire-prone, compared with a Scenic Rim Regional average of 52%.
Is Peak Crossing affected by aircraft noise?
About 2% of Peak Crossing sits inside a published aircraft noise contour, and the highest contour present is ANEF 15 - 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 Peak Crossing under a flight path?
Aircraft were observed below 3,000 ft over about 31% of Peak Crossing, and over about 85% 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 1,000 ft, with an average of 3,500 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.
