Shellharbour

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

The estimated population of Shellharbour is around 4,622 as of February 2026. This reflects an increase of 1,102 people since the 2021 Census, which reported a population of 3,520. The growth was inferred from AreaSearch's estimation of the resident population at 4,480 in June 2024, along with 52 validated new addresses since the Census date. This results in a population density of 1,894 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. Shellharbour's growth of 31.3% since the 2021 census exceeded that of Rest of NSW (5.9%) and the SA4 region. This growth was primarily driven by interstate migration contributing approximately 47.0% of overall population gains, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch is using 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 this data. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking ahead, exceptional growth is predicted over the period, placing Shellharbour in the top 10 percent of Australian non-metropolitan areas. The area is expected to grow by 1,720 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 18.3% in total over the 17 years.

Recent residential development output has been above average within Shellharbour when compared nationally

AreaSearch analysis of ABS building approval numbers shows Shellharbour experienced around 38 dwelling approvals annually. Between FY21 and FY25, approximately 193 homes were approved, with an additional 24 approved in FY26 to date. Over the past five financial years, on average, two people moved to the area for each dwelling built.

This indicates a balanced supply and demand, maintaining stable market conditions. The average construction cost value of new homes was $603,000, suggesting developers focus on the premium market with high-end developments. In FY26, commercial development approvals totalled $4.9 million, indicating limited commercial development activity compared to residential. Compared to Rest of NSW, Shellharbour exhibited moderately higher construction activity, 23.0% above the regional average per person over the past five years. This preserved buyer options while sustaining existing property demand. However, construction activity has recently eased.

Overall, developer interest in Shellharbour remains robust as it is significantly above the national average. New building activity shows a skew towards compact living, with 24.0% standalone homes and 76.0% medium to high-density housing. This shift from the current housing mix of 69.0% houses reflects reduced availability of development sites and addresses shifting lifestyle demands and affordability requirements. With around 201 people per dwelling approval, Shellharbour exhibits characteristics of a growth area. Future projections estimate Shellharbour will add 844 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting population growth beyond current projections.
