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

As of Feb 2026, the estimated population of North Wahroonga is around 2,083, a decrease of 17 people since the 2021 Census which reported a population of 2,100.

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, there has been virtually no new residential development in the area during this period. 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. The scarcity of new homes can strengthen demand and prices for existing properties. However, building activity has accelerated in recent years. Nationally, the area's development activity is below average, reflecting its maturity and possible planning constraints.
