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 Nov 2025, Chittaway Bay's estimated population is around 2,038. This reflects an increase of 51 people since the 2021 Census which reported a population of 1,987. The change was inferred from AreaSearch's resident population estimate of 1,981 following examination of ABS's latest ERP data release in June 2024 and address validation since the Census date. This results in a density ratio of 1,819 persons per square kilometer, above average national levels assessed by AreaSearch. The suburb's 2.6% growth positions it competitively with its SA4 region's 3.1%. Overseas migration contributed approximately 56% of overall population gains during recent periods.
AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2 level projections are used, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Anticipated demographic trends suggest lower quartile growth for Australian statistical areas. Chittaway Bay is expected to grow by 47 persons to 2041, reflecting a total increase of 1.6% over the 17-year period.

Development
Residential development activity is lower than average in Chittaway Bay according to AreaSearch's national comparison of local real estate markets
AreaSearch analysis of ABS building approval numbers for Chittaway Bay shows approximately one residential property granted approval per year over the past five financial years. This totals an estimated five homes. No approvals have been recorded so far in FY-26.
On average, 7.2 people move to the area annually for each dwelling built between FY-21 and FY-25. This demand significantly outpaces supply, typically putting upward pressure on prices and increasing competition among buyers. New homes are being constructed at an average cost of $541,000. Compared to Greater Sydney, Chittaway Bay records markedly lower building activity, 88.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing homes.
However, recent construction activity has intensified. The area's population is forecasted to gain 33 residents by 2041, with development keeping reasonable pace with projected growth.
