Killara (NSW)

An assessment of population growth drivers in Killara reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Feb 2026, the estimated population of the suburb of Killara (NSW) is around 11,254. This reflects a growth of 634 people since the 2021 Census, which reported a population of 10,620. The increase is inferred from AreaSearch's estimation of resident population at 11,161 as of June 2024, along with an additional 69 validated new addresses since the Census date. This results in a population density ratio of 2,462 persons per square kilometer, placing Killara in the upper quartile nationally according to AreaSearch's assessments. The suburb's growth rate of 6.0% since the 2021 census exceeds that of its SA3 area (4.3%) and SA4 region, marking it as a growth leader. Overseas migration was the primary driver of population gains in recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections where applicable, released in 2022 with 2021 as the base year. Based on these aggregations, a population increase of just below the median of national statistical areas is expected for Killara by 2041, with an estimated growth of 1,311 persons and a total gain of 10.7% over the 17 years.

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

AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Killara had around 23 new homes approved annually over the past 5 financial years, totalling an estimated 118 homes. So far in FY-26, 19 approvals have been recorded. Over these 5 years (FY-21 to FY-25), each dwelling supported an average of 2.9 new residents per year, indicating solid demand that supports property values. New homes are being built at an average expected construction cost value of $1,319,000, suggesting developers target the premium market segment with higher-end properties.

In FY-26, commercial approvals registered totalled $114.7 million, demonstrating high levels of local commercial activity. Compared to Greater Sydney, Killara has around two-thirds the rate of new dwelling approvals per person. Nationally, it places among the 26th percentile of areas assessed, offering more limited choices for buyers and supporting demand for existing dwellings. This level reflects the area's maturity and possible planning constraints.

New building activity shows 76.0% detached dwellings and 24.0% attached dwellings, sustaining Killara's suburban identity with a concentration of family homes suited to buyers seeking space. Interestingly, developers are building more traditional houses than the current mix suggests (55.0% at Census), indicating continued strong demand for family homes despite density pressures. At around 629 people per approval, Killara shows a mature, established area. Population forecasts indicate it will gain 1,203 residents through to 2041 (from the latest AreaSearch quarterly estimate). Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.
