Dean Park

Dean Park is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

The population of the suburb of Dean Park is estimated to be around 3,237 as of February 2026. This reflects an increase of 57 people from the 2021 Census figure of 3,180. The increase was inferred from AreaSearch's estimation of the resident population at 3,199 in June 2024 and the validation of eight new addresses since the Census date. This results in a population density ratio of 2,143 persons per square kilometer, which is higher than the average seen across national locations assessed by AreaSearch. Overseas migration contributed approximately 55% of overall population gains during recent periods, primarily driving population growth for the suburb.

AreaSearch adopts 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 from these aggregations are applied to all areas until 2041. Based on aggregated SA2-level projections, the suburb is expected to increase its population by 293 persons to reach 3,530 by 2041, reflecting a total increase of approximately 8% over the 17-year period.

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

AreaSearch analysis of ABS building approval numbers indicates that Dean Park has received approximately 9 dwelling approvals per year over the past five financial years, totalling around 48 homes. In FY26 so far, 10 approvals have been recorded. The area's population decline suggests that new supply is likely meeting demand, providing good choice for buyers. New properties are being constructed at an average expected construction cost value of $324,000.

This financial year has seen $34.0 million in commercial approvals, indicating high levels of local commercial activity. Compared to Greater Sydney, Dean Park shows elevated construction levels, with 16.0% above the regional average per person over the past five years. However, this is below the national average, suggesting maturity and potential planning constraints. New development consists predominantly of detached houses (91.0%) and a smaller proportion of attached dwellings (9.0%), maintaining Dean Park's traditional suburban character focused on family homes.

The area has approximately 338 people per dwelling approval, indicating a low density market. According to AreaSearch's latest quarterly estimate, Dean Park is projected to add around 255 residents by 2041. Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
