Denham Court

Denham Court lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

As of May 2026, the population of Denham Court is estimated to be around 15,828 people. This figure reflects a significant increase from the 2021 Census population of 9,129 people, representing a growth of 6,699 individuals (73.4%). AreaSearch's analysis, based on the latest ERP data release by the ABS in June 2025 and additional validated new addresses since the Census date, estimated the resident population to be 15,769. The population density ratio is calculated at 1,172 persons per square kilometer, which is comparable to averages seen across other locations assessed by AreaSearch. Notably, Denham Court's population growth of 73.4% since the 2021 Census exceeds both the state average (7.1%) and that of Greater Sydney, positioning it as a significant growth leader in the region. Interstate migration was the primary driver for this growth, contributing approximately 74.0% of overall population gains during recent periods.

However, all factors including natural growth and overseas migration showed positive contributions. AreaSearch's projections for Denham Court are based on ABS/Geoscience Australia data released in 2024 with a 2022 base year for covered SA2 areas, and NSW State Government's SA2-level projections released in 2022 with a 2021 base year for uncovered areas. These projections anticipate significant population growth in the suburb over the next two decades. By 2041, Denham Court is expected to grow by an additional 4,982 persons, reflecting a total increase of 31.1% over the 16-year period.

The level of residential development activity in Denham Court was found to be higher than 90% of real estate markets across the country

Denham Court has averaged approximately 256 new dwelling approvals per year over the past five financial years, totalling an estimated 1,281 homes. In the current financial year FY-26, 38 approvals have been recorded to date. This results in an average of around six new residents arriving per dwelling constructed annually between FY-21 and FY-25, indicating a significant demand outpacing supply. The average construction cost value for new homes is approximately $576,000, suggesting developers are targeting the premium market segment with higher-end properties.

In this financial year, commercial approvals amounting to $3.9 million have been registered, reflecting limited focus on commercial development. New developments consist of 89% detached dwellings and 11% townhouses or apartments, maintaining Denham Court's suburban identity with a concentration of family homes suited for buyers seeking space.

The area has approximately 303 people per dwelling approval, indicating potential room for growth. According to the latest AreaSearch quarterly estimate, Denham Court is projected to add around 4,923 residents by 2041. Based on current development patterns, new housing supply should readily meet demand, providing good conditions for buyers and potentially facilitating population growth beyond current projections.
