Based on ABS population updates, as of November 2025, the Killarney Heights statistical area's population is estimated at around 4,579. This reflects an increase of 77 people since the 2021 Census, which reported a population of 4,502.

Since the census, Killarney Heights has seen a growth rate of 1.7%, positioning it within 1.5 percentage points of the SA3 area's growth rate of 3.2%. Overseas migration was the primary driver of population gains 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 Killarney Heights expected to increase by 165 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 4.0% over the 17 years.
