Netherby (SA)

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

As of Feb 2026, the estimated population of the suburb of Netherby (SA) is around 1,532. This reflects an increase from the 2021 Census figure of 1,510 people, representing a rise of 22 individuals or approximately 1.5%. The current resident population estimate of 1,506 comes from AreaSearch's analysis of latest ERP data released by ABS in June 2024 and address validation since the Census date. This results in a population density ratio of 1,255 persons per square kilometer, exceeding national averages assessed by AreaSearch. Overseas migration was the primary driver behind this growth.

AreaSearch employs projections based on ABS/Geoscience Australia data for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years beyond 2032, SA State Government's Regional/LGA projections by age category are used, adjusted through weighted aggregation from LGA to SA2 levels. Future population trends suggest lower quartile growth for statistical areas analysed by AreaSearch. By 2041, the suburb of Netherby (SA) is projected to expand by 66 persons, reflecting a total increase of approximately 5.2% over the 17-year period.

AreaSearch analysis of residential development drivers sees Netherby recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis shows Netherby had approximately 10 new homes approved annually. Between FY-21 and FY-25, around 52 homes were approved, with one more in FY-26 so far. On average, about 0.6 new residents arrived per year for each new home over the past five financial years.

This suggests supply is meeting or exceeding demand, offering greater buyer choice while supporting potential population growth above projections. The average value of new homes being built was $736,000, indicating a focus on the premium segment with upmarket properties. In FY-26, there have been $1.8 million in commercial approvals, reflecting minimal commercial development activity. Compared to Greater Adelaide, Netherby has 101.0% more development activity per person.

Recent construction comprises 83.0% detached houses and 17.0% medium and high-density housing, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. Developers are constructing more detached housing than the existing pattern implies (66.0% at Census), reflecting strong demand for family homes amid densification trends. Netherby has around 72 people per dwelling approval, indicating a low-density area. According to AreaSearch's latest quarterly estimate, Netherby is projected to gain 80 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.
