Blackett

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

Based on ABS population updates and new addresses validated by AreaSearch, the population of the suburb of Blackett is estimated at around 3799 as of Feb 2026. This reflects an increase of 213 people (5.9%) since the 2021 Census, which reported a population of 3586 people. The change is inferred from the resident population of 3694 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 15 validated new addresses since the Census date. This level of population equates to a density ratio of 3219 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. The suburb's 5.9% growth since the 2021 census exceeded the SA3 area (5.2%), marking it as a growth leader in the region. Population growth for the area was primarily driven by natural growth that contributed approximately 55.00000000000001% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Moving forward with demographic trends, lower quartile growth of national statistical areas is anticipated, with the suburb expected to increase by 73 persons to 2041 based on aggregated SA2-level projections, reflecting a reduction of 0.8% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers shows Blackett has recorded around 12 residential properties granted approval annually. Over the past five financial years, from FY-21 to FY-25, approximately 62 homes were approved, with another 13 approved so far in FY-26. Despite a falling population during this period, development activity has been adequate relative to the population change, which is positive for buyers.

The average expected construction cost of new properties is $206,000, below regional levels, indicating more affordable housing choices for buyers. This financial year, $5.2 million in commercial development approvals have been recorded, suggesting the area's residential character. Compared to Greater Sydney, Blackett has slightly more development activity, with 33.0% above the regional average per person over the five-year period from FY-21 to FY-25. This preserves reasonable buyer options while sustaining existing property demand.

However, this level is still under the national average, indicating the area's established nature and suggesting potential planning limitations. Recent construction in Blackett comprises 86.0% detached dwellings and 14.0% attached dwellings, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. The location has approximately 329 people per dwelling approval, indicating a low density market. Population projections show stability or decline in Blackett, which should see reduced housing demand pressures, benefiting potential buyers.
