AreaSearch is adopting 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 years 2032 to 2041. By 2041, the suburb is expected to grow by approximately 362 persons based on aggregated SA2-level projections, reflecting an increase of 6.5% over the 17-year period.
