About this area and its boundary

How many people will live around hereofficial forecast
How many people will live around here
The rest of this page looks backwards. This is the one number that looks forward - and it is the state government's own, not ours. Travel Zone Projections 2024 (Transport for NSW) projects the The Hills Shire council area, which contains Castle Hill - South along with its neighbouring suburbs, to grow to 329,810 people by 2041: 135,930 more people than the 193,880 counted in 2021.
This is the council area, not Castle Hill - South. The Hills Shire is a whole local government area covering many suburbs, and neither state publishes a projection for a single suburb. Growth is never spread evenly across a council - a greenfield estate and an established street inside the same council will move very differently - so read this as the direction of the wider area a suburb sits in, not as a forecast for its own streets. Only the years the publisher itself lists are plotted: nothing is filled in between them, and nothing is carried past 2041. A projection is an assumption about the future, not a measurement of it, and it will be revised - this one was released 2024. These figures sit on the projection's own series, so they are not directly comparable with the ABS resident-population and Census counts elsewhere on this page, which use different geographies and different years.

All 9 checks and what each one means
Flooding
Not publishedNew South Wales publishes flood planning maps council by council, with no free statewide layer we can republish - check the local council's flood planning map for this area.
Bushfire
Designated Bush Fire Prone LandPresent in this area
Part of this area is mapped as Bush Fire Prone Land by the NSW Rural Fire Service. This designation is drawn broadly around vegetation across most of NSW, so read it as "check the property", not as a measure of how exposed the area is.
Heritage controls
In an official overlayPresent in this area
Part of this area sits inside the heritage layer in the local environmental plan, so changes to buildings there - extensions, demolition, sometimes even paint colours - need planning approval. It applies property by property: most homes in an area with an overlay are not in it, and being in one is a protection as much as a restriction. Almost every NSW area contains some heritage-listed land, so read this as "check the address", not as something that sets this area apart.
Traffic noise
Main roads onlyOld Northern Road · Castle Hill Road · Terminus Street · +3 more
No freeway or highway is mapped inside this area. 6 named main roads (arterial or connector) run through it. Roads are counted by name, not by mapped segment.
Aircraft noise
Not mappedNew South Wales maps aircraft-noise contours only where a council or precinct plan writes them in - four councils and the Western Sydney Airport precinct do. Sydney Airport's contours are published federally in its master plan and are not in the state layer, so read this as "nothing mapped here", not as a quiet area.
Land contamination checks
Not mappedNew South Wales records contaminated land in the EPA's searchable register of notified sites rather than in a planning-scheme map layer, so we have no overlay to show for this area. Search the NSW EPA contaminated land record for a specific address - nothing mapped here means we have not checked it, not that the land is clear.
Acid sulfate soils
None mappedNew South Wales classifies acid sulfate soils in the planning instruments of its coastal and estuarine councils only, and none is mapped in this area. These soils form in low-lying coastal sediments, so away from the coast and the estuaries there is nothing to map - read this as outside the mapped zone rather than as a soil test.
Recorded crime
Official counts published1,414 incidents
Police-recorded criminal incidents in Calendar years; latest = Jan-Dec 2025, down 21% on the prior year. A count, not a rate - busier areas with more shops, stations and visitors record more incidents than quiet ones of the same size. Full breakdown ↑

Share of occupied private dwellings here with a stated tenure (Census 2021). The middle NSW area is 1.6% public and 0.7% community, across 624 areas. Listed because families ask; it is a fact about who owns the homes, not a judgement about the people in them.
