Northbridge (NSW)

An assessment of population growth drivers in Northbridge reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Nov 2025, Northbridge's population is estimated at around 6464 people. This reflects a decrease of 29 people since the 2021 Census, which reported a population of 6493 people. The current estimate is based on AreaSearch's analysis of ABS population updates and new addresses validated by them following examination of the latest ERP data release by the ABS in June 2024. This level of population equates to a density ratio of 2411 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Overseas migration was primarily responsible for population growth in recent periods.

AreaSearch is adopting 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 released in 2022 with a base year of 2021 for areas not covered by the former data. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. According to population projections, Northbridge is expected to increase by 5 persons by 2041 based on aggregated SA2-level projections, reflecting a gain of 0.2% in total over the 17 years.

The level of residential development activity in Northbridge is very low in comparison to the average area assessed nationally by AreaSearch

Northbridge has had approximately 8 residential properties approved annually over the past five financial years, totalling an estimated 41 homes. As of FY26, 2 approvals have been recorded. Despite a population decline during this period, housing supply has remained adequate relative to demand, resulting in a balanced market with diverse buyer choices.

The average construction cost value for new homes is $1,352,000, indicating developers' focus on the premium market. Compared to Greater Sydney, Northbridge has significantly less development activity, which is 80.0% below the regional average per person. This limited supply generally supports stronger demand and values for established dwellings. Nationally, Northbridge's development level is also lower, reflecting a mature market and possible development constraints. New developments consist of 56.0% detached houses and 44.0% townhouses or apartments, marking a shift from the current housing pattern of 74.0% houses. This change suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs.

With around 807 people per dwelling approval, Northbridge reflects a highly mature market. Future projections indicate Northbridge adding 11 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
