AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Over this period, projections indicate a decline in overall population, with the area's population expected to shrink by 458 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, which is projected to increase by 636 people.
