Gymea

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Gymea's population is estimated at around 8,398 as of Feb 2026. This reflects an increase of 179 people (2.2%) since the 2021 Census, which reported a population of 8,219 people. The change is inferred from the resident population of 8,385, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 53 validated new addresses since the Census date. This level of population equates to a density ratio of 3,870 persons per square kilometer, placing Gymea in the top 10% of national locations assessed by AreaSearch. Over the past decade, Gymea has demonstrated resilient growth patterns with a compound annual growth rate of 0.8%, outpacing the SA4 region. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 56% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises the NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Considering projected demographic shifts, a population increase just below the median is expected for Gymea, with an anticipated growth of 453 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of approximately 5.2% in total over the 17 years.

AreaSearch analysis of residential development drivers sees Gymea recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers in Gymea shows an average of approximately 38 dwelling approvals per year over the past five financial years, totalling around 191 homes. As of FY-26, 26 approvals have been recorded. The average number of new residents arriving per new home has been around 0.9 per year between FY-21 and FY-25. This suggests that supply is meeting or exceeding demand, offering greater buyer choice while supporting potential population growth above projections.

The average construction cost value of new homes over the past five financial years was approximately $522,000, indicating a focus on the premium segment with upmarket properties. In FY-26, commercial approvals totalling $1.7 million have been registered, reflecting the area's residential nature. New development in Gymea consists of 29% detached dwellings and 71% medium to high-density housing. This shift from existing housing patterns (currently 45% houses) suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs.

Gymea has a population density of around 224 people per approval, reflecting a low-density area. According to the latest AreaSearch quarterly estimate, Gymea is projected to gain approximately 440 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

Employment performance in Gymea ranks among the strongest 15% of areas evaluated nationally

Gymea has an educated workforce with professional services well-represented. Its unemployment rate was 2.0% in December 2025, below Greater Sydney's 4.2%. Workforce participation is similar to Greater Sydney at 70.2%.

Notably, 43.1% of residents work from home, potentially influenced by Covid-19 lockdowns. Key industries are health care & social assistance, construction, and professional & technical services. Construction stands out with an employment share 1.3 times the regional level. Conversely, accommodation & food is under-represented at 4.3% compared to Greater Sydney's 5.8%.

Local employment opportunities appear limited as indicated by Census data comparing working population to resident population. Between December 2024 and December 2025, employment increased by 0.4%, labour force by 0.6%, leading to a 0.2 percentage point rise in unemployment. In contrast, Greater Sydney saw employment growth of 2.2% and labour force growth of 2.3%. Jobs and Skills Australia's national employment forecasts from May-25 project national employment expansion by 6.6% over five years and 13.7% over ten years. Applying these projections to Gymea's industry mix suggests local employment could increase by 6.8% over five years and 13.8% over ten years, though this is a simplified extrapolation for illustrative purposes.
