AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered, NSW State Government's SA2 level projections are used, 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. According to this methodology, the area's population is expected to decline by 267 persons by 2041. However, growth across specific age cohorts is anticipated, with the 85 and over age group projected to expand by 131 people.
