This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
Chittaway Bay is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends
As of 1 Nov 2025, the estimated population for the Chittaway Bay statistical area (Lv2) is around 1,962, a decrease of 25 people since the 2021 Census which reported 1,987 residents. This reduction reflects a change inferred from AreaSearch's estimate of 1,958 residents following their analysis of the latest ERP data release by the ABS in Jun 2024 and address validation since the Census date. The population density stands at approximately 1,751 persons per square kilometer, exceeding national averages assessed by AreaSearch. Overseas migration contributed roughly 56% to overall population gains during recent periods. AreaSearch employs ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022; for areas not covered, NSW State Government's SA2 level projections from 2022 using 2021 as the base year are utilized.
Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, the area is projected to grow by 45 persons, reflecting a total increase of approximately 5.5% over the 17-year period.
Frequently Asked Questions - Population
Development
The level of residential development activity in Chittaway Bay is very low in comparison to the average area assessed nationally by AreaSearch
Chittaway Bay has not had any residential development approvals in the past five years. This indicates that the area is largely built out with limited vacant land available for new developments. Established areas like Chittaway Bay often experience steady demand for existing properties due to the lack of new-build alternatives.
Compared to Greater Sydney, Chittaway Bay has significantly less development activity. The scarcity of new homes typically increases demand and prices for existing properties in such areas. This is also below average nationally, suggesting maturity and possible planning constraints in the area.

A proposed 30 ML/day reverse osmosis desalination plant to be built adjacent to the existing Toukley Sewage Treatment Plant. The project is a key drought response initiative under the Central Coast Water Security Plan, designed to be 'plan ready' with approvals in place for rapid construction if dam levels fall below critical triggers (currently 45% storage). It features a direct ocean intake structure located offshore between Noraville and Magenta to minimize beach impact and will provide a climate-independent water supply for up to 250,000 residents.

Following the 2025 business case evaluation, the project has moved into a two-year Development Phase focusing on design refinement (to 40% maturity), securing planning approvals, and corridor preservation. The route includes approximately 115km of tunneling and six planned stations: Broadmeadow, Lake Macquarie, Gosford, Sydney Central, Parramatta, and Western Sydney International Airport.
