Between 2021 and 2025, Blackett's growth rate of 3.3% exceeded the SA3 area's 3.1%, indicating its status as a regional growth leader. Natural growth accounted for approximately 55% of overall population gains during recent periods.

AreaSearch projects future growth based on ABS/Geoscience Australia projections released in 2024, with a base year of 2022, and NSW State Government's SA2 level projections released in 2022, with a base year of 2021 for areas not covered by ABS data. By 2041, the suburb is expected to increase by 61 persons based on aggregated SA2-level projections, reflecting steady growth over the 17-year period.

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

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Blackett has recorded around 11 residential properties granted approval annually. Over the past five financial years, between FY-21 and FY-25, approximately 56 homes were approved, with a further 7 approved so far in FY-26. On average, over these five years, 0.1 new residents arrived per new home built, indicating that supply is meeting or exceeding demand, providing greater buyer choice while supporting potential population growth above projections.

The average construction value of new properties was $206,000, which is under regional levels, suggesting more accessible housing choices for buyers. In FY-26, Blackett has recorded $2.0 million in commercial development approvals, indicating a predominantly residential focus. Compared to Greater Sydney, Blackett has slightly more development activity, with 20.0% above the regional average per person over the five-year period from FY-21 to FY-25. This level of development preserves reasonable buyer options while sustaining existing property demand.

However, it is also under the national average, suggesting that the area is established and may have potential planning limitations. Recent construction in Blackett comprises 85.0% detached dwellings and 15.0% attached dwellings, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. The location has approximately 269 people per dwelling approval, indicating a low-density market. Population projections for Blackett show stability or decline, which should result in reduced housing demand pressures, benefiting potential buyers.
