Population
Heathcote 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 November 2025, the estimated population of Heathcote is around 6,197 people. This figure reflects an increase from the previous population count of 6,148 in the 2021 Census, marking a growth of 49 individuals (0.8%). AreaSearch, following examination of the latest ERP data release by the ABS in June 2024 and validation of new addresses since the Census date, estimated the resident population to be 6,186 people. This results in a population density ratio of 609 persons per square kilometer for Heathcote. The suburb's growth rate since the census is 0.8%, which is within 1.8 percentage points of the SA3 area's growth rate of 2.6%. Overseas migration was the primary driver of this population increase in recent periods.
AreaSearch adopted 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 utilized NSW State Government's SA2 level projections released in 2022 with a base year of 2021. These projections indicate that Heathcote is expected to increase by 267 persons to reach an estimated population of 6,464 by the year 2041. This projected growth reflects a total gain of 3.8% over the 17-year period from 2025 to 2041.

Development
AreaSearch assessment of residential development drivers sees a low level of activity in Heathcote, placing the area among the bottom 25% of areas assessed nationally
AreaSearch analysis of ABS building approval numbers indicates Heathcote has received around 25 dwelling approvals annually. Between FY-21 and FY-25, approximately 125 homes were approved, with another 7 in FY-26 so far. Despite population decline, development activity has been adequate relative to other areas.
New properties are constructed at an average cost of $680,000, slightly above the regional average. This year, there have been $1.4 million in commercial approvals, suggesting a predominantly residential focus. Compared to Greater Sydney, Heathcote has seen 28.0% more development per person over the past five years. Building activity has slowed recently, with new developments consisting of 32.0% detached houses and 68.0% medium and high-density housing. This shift from the area's existing housing (74.0% houses) indicates decreasing developable sites and changing lifestyles.
The current population per dwelling approval is estimated at 536 people. Population forecasts suggest Heathcote will gain 235 residents by 2041, with new housing supply expected to meet demand based on current development patterns.
