For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking ahead with demographic trends, lower quartile growth of national statistical areas is anticipated. The suburb is expected to increase by 44 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of approximately 0.9% in total over the 16 years.

Residential development activity is lower than average in Blackett according to AreaSearch's national comparison of local real estate markets

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Blackett has recorded around 12 residential properties granted approval annually. Over the past 5 financial years, from FY-21 to FY-25, approximately 62 homes were approved, with a further 14 approved so far in FY-26. On average, over these years, 1.4 new residents arrived per year for each new home built, indicating balanced supply and demand conditions. However, this figure has increased to 4.4 people per dwelling over the past 2 financial years, suggesting heightened demand and tightening supply.

New homes are being constructed at an average expected cost of $206,000, which is below regional levels, offering more affordable housing options for buyers. In FY-26 alone, $5.2 million in commercial development approvals have been recorded, reflecting the area's residential character. Compared to Greater Sydney, Blackett has seen slightly higher development activity over the past 5 years, with a 34.0% increase above the regional average per person. This level is still below the national average, suggesting an established nature for the area and potential planning limitations.

Recent construction comprises predominantly detached dwellings at 86.0%, with attached dwellings making up the remaining 14.0%. This sustains Blackett's suburban identity, offering more space suited to family homes buyers. Population forecasts indicate that Blackett will gain approximately 31 residents by 2041, based on the latest AreaSearch quarterly estimate. Given current development patterns, new housing supply is expected to readily meet demand, providing good conditions for buyers and potentially facilitating further population growth beyond current projections.
