Banksia

Banksia 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 AreaSearch validations for the suburb of Banksia, its estimated population was around 3,843 as of Feb 2026. This reflected an increase of 566 people since the 2021 Census, which reported a population of 3,277. The change was inferred from AreaSearch's resident population estimate of 3,794 following examination of the latest ERP data release by the ABS (June 2024) and an additional validated new address since the Census date. This level of population resulted in a density ratio of 4,003 persons per square kilometer, placing Banksia in the top 10% of national locations assessed by AreaSearch. The suburb's 17.3% growth since the 2021 census exceeded both the SA4 region (7.6%) and the SA3 area, marking it as a growth leader. Population growth was primarily driven by overseas migration contributing approximately 88.0% of overall population gains during recent periods.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area released in 2024 with 2022 as the base year. For areas not covered, NSW State Government's SA2 level projections released in 2022 with 2021 as the base year were utilized. Growth rates by age group from these aggregations were applied to all areas for years 2032 to 2041. Future population dynamics projected an above median growth, with Banksia expected to grow by 959 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 23.7% over the 17 years.

Residential development activity is slightly higher than average within Banksia when compared nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Banksia recorded around 7 residential properties granted approval per year. Over the past 5 financial years, between FY-21 and FY-25, approximately 36 homes were approved, with 1 so far in FY-26. On average, for every home built over these years, there are about 6.8 new residents.

This indicates demand significantly outpacing supply, which typically puts upward pressure on prices and increases competition among buyers. New properties are constructed at an average expected cost of $410,000. In FY-26, commercial development approvals totalled $5.5 million, reflecting the area's primarily residential nature. Compared to Greater Sydney, Banksia has significantly less development activity, being 63.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing dwellings, though recent periods have seen an increase in development activity. Nationally, this is also lower, reflecting market maturity and possible development constraints. New building activity shows 12.0% detached dwellings and 88.0% townhouses or apartments, marking a significant departure from the current housing pattern of 78.0% houses.

This trend suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs. Banksia reflects a transitioning market with around 329 people per approval. Future projections show Banksia adding 910 residents by 2041, based on the latest AreaSearch quarterly estimate. If current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.
