A planning-constraint profile of South Mackay
(Mackay Regional, QLD) - 7.21 km², mapped from live council and
state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
7.21 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to South Mackay'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.

Aircraft noise and flight paths over South Mackay
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
48% 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
- Mackay Regional Council ANEF
Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 4 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.

South Mackay planning - frequently asked
Is South Mackay flood-prone?

Across the suburb, 91% of the 3,610 properties we analysed carry some level of mapped flood risk, including 3 rated high risk or historically affected.

Is South Mackay bushfire-prone?
Around 3% of South Mackay is mapped as bushfire-prone, compared with a Mackay Regional average of 26%.
Is South Mackay affected by aircraft noise?
About 48% of South Mackay 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 South Mackay under a flight path?
Aircraft were observed below 3,000 ft over about 100% of South Mackay, in the period sampled (4 Sep 2026 to 7 Nov 2026). The lowest measured aircraft was at 500 ft, with an average of 500 ft. At the busiest point in the suburb about 48 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.
