Natural growth contributed about 68% of overall population gains during recent periods. 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 with a base year of 2021 are utilized. Growth rates by age group are applied to all areas for years 2032 to 2041. By 2041, the suburb is projected to increase by 25 persons based on aggregated SA2-level projections, reflecting an overall increase of 0.3% over the 17-year period.
