As of Feb 2026, the estimated population of the suburb of Killarney Heights is around 4,603. This figure reflects an increase of 101 people since the 2021 Census, which reported a population of 4,502 people.

The suburb's 2.2% growth since the census is within 1.1 percentage points of the SA3 area's 3.3%, indicating competitive growth fundamentals. Overseas migration was the primary driver of population gains in recent periods.

AreaSearch is using ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas from 2032 to 2041. Future population trends anticipate lower quartile growth nationally, with the suburb expected to increase by 177 persons to 2041, reflecting an overall increase of 3.3% over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Killarney Heights, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Killarney Heights averaging around 15 new dwelling approvals each year over the past five financial years, totalling an estimated 75 homes. By FY-26, 5 approvals have been recorded. Over these five years, new construction has matched or outpaced demand, with an average of 0.7 new residents per year per dwelling constructed. This has offered buyers more options and enabled population growth that could exceed current expectations.

The average value of new properties constructed is $866,000, indicating a focus on the premium segment. In FY-26, $53,000 in commercial approvals have been registered, demonstrating the area's residential nature. Relative to Greater Sydney, Killarney Heights has slightly more development, with 11.0% above the regional average per person over the five-year period. This maintains good buyer choice while supporting existing property values, though recent periods show a moderation in development activity.

The national average is higher than Killarney Heights' level, indicating the area's established nature and suggesting potential planning limitations. Recent development has been entirely comprised of standalone homes, maintaining the area's traditional suburban character with a focus on family homes. With around 1526 people per approval, Killarney Heights shows a mature, established area. Future projections estimate an addition of 151 residents by 2041, based on AreaSearch's latest quarterly estimate. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
