Has Peak Crossing flooded? Flood history and overland flow

Yes. Recorded flood mapping reaches into Peak Crossing: 2 of the 83 properties we analysed (2.4%) sit at least partly inside a mapped historical flood extent. The free address check says whether a given lot is inside one.

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

7% 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

ANEF 20

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.

Night movements: observed, lowest 4,500 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.

Peak Crossing planning - frequently asked

Is Peak Crossing flood-prone?

About 12% of Peak Crossing falls within a mapped flood overlay, against the council-wide suburb average of 46%. Across the suburb, 31% of the 83 properties we analysed carry some level of mapped flood risk, including 17 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?

Is Peak Crossing bushfire-prone?

Around 77% of Peak Crossing is mapped as bushfire-prone, compared with a Ipswich City average of 50%.

Is Peak Crossing affected by aircraft noise?

About 7% of Peak Crossing sits inside a published aircraft noise contour, and the highest contour present is ANEF 20 - under AS 2021, land between ANEF 20 and 25 is conditionally acceptable for houses, usually with noise attenuation in the build.

Aircraft were observed below 3,000 ft over about 50% of Peak Crossing, and over about 77% 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 3,000 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.
