Population
Windang has shown very soft population growth performance across periods assessed by AreaSearch
Windang's population, as of November 2025, is estimated at approximately 2,606 people. This figure reflects a decrease from the 2021 Census count of 2,610 people, indicating a drop of 4 individuals (0.2%). AreaSearch validated this estimate through examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. The population density ratio is around 1,099 persons per square kilometer, aligning with averages seen across locations assessed by AreaSearch. Overseas migration primarily drove Windang's population growth during recent periods.
For projections, AreaSearch uses ABS/Geoscience Australia estimates 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 with a base year of 2021 are utilized. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. According to these projections, Windang's population is expected to decline by 10 persons by 2041. However, specific age cohorts like the 25 to 34-year-olds are anticipated to grow, with a projected increase of 50 people in this group over this period.

Development
The level of residential development activity in Windang is very low in comparison to the average area assessed nationally by AreaSearch
Windang has seen minimal development activity with an average of less than one approval per year over the past five years, totaling just one approval during this period. This limited development reflects Windang's rural nature where housing needs drive development rather than broad market demand. The small sample size means individual projects can significantly impact annual growth and relativity statistics.
Compared to Rest of NSW, Windang has notably less construction activity. Its development pattern is also below national averages.

It is located at least 20 km offshore and has the potential to generate up to 2.9 GW of renewable energy, enough to power 1.8 million homes. Feasibility Licence applications were open until August 15, 2024. However, the one application received has been paused, and other potential developers (BlueFloat Energy, Equinor/Oceanex) have withdrawn interest, leaving the future of the zone uncertain, but the area remains declared.
Illawarra Offshore Wind Zone
Commonwealth-declared offshore wind zone located 20-45 km off the Illawarra coast between Wombarra and Kiama, NSW. Covers 1,022 kmý with potential for approximately 2.9 GW of generation capacity.

The May 2025 Illawarra REZ Roundtable and Registration of Interest process attracted 44 projects worth over $43 billion in potential investment (including offshore wind, solar, energy storage, pumped hydro, and hydrogen). EnergyCo is the infrastructure planner, coordinating transmission upgrades in partnership with Endeavour Energy.
Rail Service Improvement Program (Mortdale-Kiama)
The Rail Service Improvement Program (formerly More Trains, More Services) is a multi-billion-dollar NSW Government initiative to simplify and modernise the rail network.

Illawarra Offshore Wind Farm
Initial Oceanex proposal for a floating offshore wind project of up to 2,000 MW located roughly 20-30 km off the Illawarra coast (Wollongong/Port Kembla, NSW). The Commonwealth declared the Illawarra offshore wind area on 15 June 2024 and opened feasibility licence applications from 17 June to 15 August 2024. Reporting in late 2024 indicated Oceanex and Equinor did not proceed with a feasibility application in Illawarra; in early 2025 other proponents signaled requests to delay licence decisions. As at early 2025, no Illawarra project by Oceanex has an awarded feasibility licence; the area remains declared and subject to ongoing assessment and consultation.
