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

As of November 2025, the estimated population for the North Wahroonga statistical area (Lv2) is around 2,082 people. This reflects a decrease since the 2021 Census, which reported a population of 2,100 people. The current estimate is based on AreaSearch's validation of new addresses and analysis of the latest ERP data release by the ABS in June 2024. This level of population results in a density ratio of 535 persons per square kilometer. Overseas migration was the primary driver of population growth in recent periods for North Wahroonga (SA2).

AreaSearch is using projections from ABS/Geoscience Australia 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. These projections indicate that the North Wahroonga (SA2) is expected to increase by 144 persons to reach 2,226 by 2041, reflecting an increase of approximately 7.9% over the 17-year period.

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 seen only one residential development approval in the past five years. Despite its established nature, the area has seen virtually no new residential development. This limited supply of new housing 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 has significantly less development activity, which can strengthen demand and prices for existing properties. However, building activity has accelerated in recent years. Nationally, this is below average, reflecting the area's maturity and possible planning constraints.
