AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Based on aggregated SA2-level projections, a significant population increase is forecasted for Gregory Hills, with an expected increase of 3,599 persons to 2041, reflecting a total increase of 20.7% over the 17 years.

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

This totals an estimated 880 homes from FY-21 to FY-25. As of FY-26, 49 approvals have been recorded. On average, each home built accommodates six new residents annually during this period, indicating demand outpaces supply, which can put upward pressure on prices and increase competition among buyers.
