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, AreaSearch utilises 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 the years 2032 to 2041. Future population trends indicate significant growth, with Wolli Creek expected to increase by approximately 4,500 persons by 2041, reflecting a total increase of 36.3% over the 17-year period based on the latest annual ERP population numbers.

The level of residential development activity in Wolli Creek was found to be higher than 90% of real estate markets across the country

Wolli Creek has averaged approximately 60 new dwelling approvals annually. Over the past five financial years, from FY21 to FY25, a total of 302 homes were approved, with no approvals yet recorded in FY26. Each year, an average of 9.8 people have moved into the area for each dwelling built during these years.

This significant demand outpaces supply, which typically influences prices upwards and intensifies competition among buyers. The average value of new homes being constructed is $306,000, lower than regional levels, suggesting more affordable housing options for buyers. In FY26, $848,000 in commercial development approvals have been recorded, indicating a primarily residential focus.

Compared to Greater Sydney, Wolli Creek's new home approvals per capita are comparable, maintaining market balance with surrounding areas despite increased building activity in recent years. All recent development has consisted of attached dwellings, promoting higher-density living and providing more affordable entry points for downsizers, investors, and first-home buyers. By 2041, Wolli Creek is projected to grow by 4,487 residents, according to the latest AreaSearch quarterly estimate. If current development rates persist, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.
