Port Botany zoning & planning overlays
A planning-constraint profile of Port Botany
(Randwick, NSW) - 2.25 km², mapped from live council and
state overlay data. This suburb is relatively unconstrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.

Constraint readout
2.25 km² - this suburb is relatively unconstrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.
Elevation hillshade with street names, clipped to Port Botany's boundary, with the 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. No flood layer is drawn because we hold no flood mapping for this area.

Aircraft noise and flight paths over Port Botany
Two different things, kept apart on purpose. The ANEF contour is the planning instrument - a forecast published per airport that planning schemes use to control noise-sensitive development. Observed overflight is what a sampled aircraft-tracking feed actually recorded over the suburb - where aircraft flew, how low and how often.
Inside an aircraft noise contour
36% 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 25 and 30 is generally unacceptable for new houses; 20 to 25 is conditionally acceptable with noise attenuation. The contour is a forecast, not a measurement at any one house.

Observed overflight - sampled 4 Sep to 2 Oct 2026
typical observed square 2 a day
Night movements: observed, lowest 1,500 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.
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.

How Port Botany is zoned
Buying in Port Botany? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 2.25 km², Port Botany is relatively unconstrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. There are 3 heritage-listed sites on record, and the dominant land-use zone is Special Activities. The median lot measures about 21,362 m² across 36 parcels.

Is Port Botany flood-prone?
We don't yet hold flood mapping covering Port Botany, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. Randwick is the authority to check for flood mapping in this area.
Is Port Botany bushfire-prone?
Bushfire mapping covers Port Botany and little to none of it is mapped as bushfire-prone.
Is Port Botany affected by aircraft noise?
About 36% of Port Botany sits inside a published aircraft noise contour, and the highest contour present is ANEF 25 - 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 Port Botany under a flight path?
Aircraft were observed below 3,000 ft over about 100% of Port Botany, in the period sampled (4 Sep 2026 to 2 Oct 2026). The lowest measured aircraft was at 500 ft, with an average of 2,000 ft. At the busiest point in the suburb about 50 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.
What is the zoning in Port Botany?
