Killarney Heights 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, Killarney Heights' population is estimated at around 4,578, reflecting an increase of 76 people since the 2021 Census. The suburb's population was reported as 4,502 in the 2021 Census. This growth is inferred from AreaSearch's estimate of 4,577 residents following examination of the latest ERP data release by the ABS (June 2024) and address validation since the Census date. The population density ratio is 1,079 persons per square kilometer, in line with averages seen across locations assessed by AreaSearch. Killarney Heights' 1.7% growth since census positions it within 1.5 percentage points of the SA4 region's 3.2%, demonstrating competitive growth fundamentals. Overseas migration primarily drove population growth for the area during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, 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. Future population trends anticipate lower quartile growth across statistical areas nationally, with the suburb expected to increase by 166 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 4.0% over the 17 years.

Residential development activity is lower than average in Killarney Heights according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis shows Killarney Heights averaging around 17 new dwelling approvals annually over the past five financial years, totalling an estimated 88 homes. As of FY26, 7 approvals have been recorded. Over these five years, an average of 0.8 new residents per year per dwelling constructed has been noted. This indicates that new construction is meeting or exceeding demand, providing more options for buyers and potentially enabling population growth beyond current expectations.

The average expected construction cost value of new properties in the area is $866,000, suggesting a focus on the premium segment with upmarket properties. This financial year has seen $53,000 in commercial approvals, reflecting the residential nature of the area. Compared to Greater Sydney, Killarney Heights has slightly more development, at 32.0% above the regional average per person over the five-year period.

This maintains good buyer choice while supporting existing property values, although recent periods have seen a moderation in development activity. New development consists of 92.0% detached dwellings and 8.0% attached dwellings, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. The location has approximately 367 people per dwelling approval, indicating an established area. Future projections estimate Killarney Heights to add 185 residents by 2041, based on the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
