Population growth drivers in Gerringong are above average based on AreaSearch's ranking of recent, and medium to long-term trends

The population of the suburb of Gerringong is estimated to be around 4,146 as of February 2026. This reflects a decrease from the previous count of 4,165 people recorded in the Census of 2021, indicating a drop of 19 individuals or approximately 0.5%. The latest resident population estimate by AreaSearch is 4,080, based on an examination of the ABS's ERP data release from June 2024 and validation of 27 new addresses since the Census date. This results in a population density ratio of 381 persons per square kilometer. Overseas migration was the primary driver of population growth in recent periods for Gerringong.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2 level projections from 2022 using a base year of 2021 are applied. Growth rates by age group from these aggregations are used for all areas between the years 2032 and 2041. According to demographic trends, Gerringong is projected to experience above median population growth for Australia's regional areas. By 2041, the suburb is expected to have expanded by 497 persons, reflecting a total gain of 10.4% over the 17-year period.

AreaSearch assessment of residential development drivers sees a low level of activity in Gerringong, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Gerringong has experienced around 13 dwellings receiving development approval each year. Approximately 65 homes were approved over the past five financial years, from FY-21 to FY-25, with another 8 approved so far in FY-26. The population decline in recent years suggests new supply has likely kept up with demand, offering good choice to buyers.

New dwellings are developed at an average expected construction cost of $1,062,000, indicating a focus on the premium segment with upmarket properties. This financial year, $1.5 million in commercial development approvals have been recorded, suggesting a predominantly residential focus. Compared to Rest of NSW, Gerringong records markedly lower building activity, at 65.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing homes, though development activity has picked up in recent periods. This activity is similarly under the national average, indicating the area's established nature and suggesting potential planning limitations.

New development consists of 79.0% detached dwellings and 21.0% townhouses or apartments, preserving the area's low density nature with an emphasis on detached housing attracting space-seeking buyers. The location has approximately 236 people per dwelling approval, indicating a low density market. Looking ahead, Gerringong is expected to grow by 431 residents through to 2041, according to the latest AreaSearch quarterly estimate. Development appears to be keeping reasonable pace with projected growth, though buyers may face increasing competition as the population expands.

AreaSearch analysis reveals Gerringong significantly outperforming the majority of regions assessed nationwide

Gerringong's workforce is well-educated with prominent representation in essential services sectors. The unemployment rate was 2.3% as of December 2025, lower than Regional NSW's 3.9%. Employment stability has been relative over the past year, according to AreaSearch aggregation of statistical area data.

As of December 2025, 2,116 residents were employed with a workforce participation rate of 63.6%, compared to Regional NSW's 61.3%. Census responses indicated that 29.6% of residents worked from home, potentially influenced by Covid-19 lockdowns. Employment is concentrated in health care & social assistance, education & training, and construction. The area shows strong specialization in education & training with an employment share 1.3 times the regional level, while agriculture, forestry & fishing has limited presence at 1.4% compared to Regional NSW's 5.3%.

Employment opportunities locally may be limited as indicated by the count of Census working population versus resident population. Between December 2024 and December 2025, employment levels increased by 0.5%, labour force by 0.4%, leaving unemployment broadly flat. In contrast, Regional NSW experienced an employment decline of 1.2% and a labour force decline of 0.8%, with unemployment rising by 0.4 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project national employment growth of 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between industry sectors. Applying these projections to Gerringong's employment mix suggests local employment should increase by 6.9% over five years and 14.1% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
