Shellharbour

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

The population of the suburb of Shellharbour is estimated at around 4,553 as of May 2026. This reflects an increase of 1,033 people since the 2021 Census, which reported a population of 3,520 people in the suburb. The change is inferred from the resident population of 4,526 estimated by AreaSearch following examination of the latest ERP data release by the ABS (June 2025) and an additional 49 validated new addresses since the Census date. This level of population equates to a density ratio of 1,866 persons per square kilometer in the suburb. Shellharbour's growth rate of 29.3% since the 2021 census exceeded that of the Rest of NSW (4.9%) and the SA4 region. Population growth for the suburb was primarily driven by interstate migration contributing approximately 47.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Exceptional growth, placing in the top 10 percent of Australian non-metropolitan areas, is predicted over the period with the suburb expected to grow by 2,097 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 45.5% in total over the 16 years.

AreaSearch assessment of residential development activity positions Shellharbour among the top 25% of areas assessed nationwide

Shellharbour experienced approximately 38 dwelling approvals annually based on AreaSearch analysis of ABS building approval numbers. Between FY-21 and FY-25, around 192 homes were approved, with an additional 29 approved in FY-26. Each year, about 4.6 people moved to the area per dwelling built over these five years.

This significant demand outpaces supply, potentially driving up prices and increasing competition among buyers. The average construction value of new homes is $603,000, indicating a focus on premium developments. Commercial development approvals totalled $4.9 million in FY-26, suggesting limited commercial development activity. Compared to the rest of NSW, Shellharbour shows moderately higher construction activity, around 16.0% above the regional average per person over the past five years. However, recent construction activity has eased.

New developments consist of approximately 24.0% detached houses and 76.0% medium to high-density housing. This shift from the current housing mix (69.0% houses) reflects reduced development site availability and addresses changing lifestyle demands and affordability requirements. Shellharbour's population is forecasted to grow by 2,070 residents by 2041. If current construction levels persist, housing supply may lag behind population growth, potentially intensifying buyer competition and supporting price growth.
