North Wahroonga

North Wahroonga has seen population growth performance typically on par with national averages when looking at short and medium term trends

As of May 2026, the estimated population of the suburb of North Wahroonga is around 2,066 people. This reflects a decrease from the 2021 Census figure of 2,100 people, a change inferred from AreaSearch's estimation of the resident population at 2,060 based on the latest ERP data release by the ABS in June 2025 and one validated new address since the Census date. This results in a population density ratio of 531 persons per square kilometer. Overseas migration was the primary driver of population growth in recent periods for North Wahroonga. AreaSearch is using projections from ABS/Geoscience Australia released in 2024 with a base year of 2022 for SA2 areas, 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.

Applying growth rates by age group from these aggregations to all areas, North Wahroonga is expected to have a population increase just below the median of Australian statistical areas by 2041. According to aggregated SA2-level projections, the suburb is expected to expand by 137 persons by that year, reflecting a gain of 6.3% in total over the 16 years.

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

North Wahroonga has had minimal residential development over the past five years, with just one approval. Despite its established nature, the area has seen virtually no new housing construction during this period. This limited supply of new dwellings typically supports values for existing properties.

Factors such as planning constraints or limited market activity may contribute to this trend. Compared to Greater Sydney, North Wahroonga shows substantially reduced residential construction activity over these five years. This constrained new construction usually reinforces demand and pricing for existing dwellings in the area. However, construction activity has intensified recently. Nationally, the level of new construction is also below average, reflecting the maturity of the area and possible planning constraints.
