Colebee

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Colebee's population is estimated at around 6,009 as of Feb 2026. This reflects an increase of 1,095 people (22.3%) since the 2021 Census which reported a population of 4,914 people. The change was inferred from AreaSearch's estimation of the resident population at 6,008 following examination of the latest ERP data release by the ABS in June 2024 and an additional 137 validated new addresses since the Census date. This level of population equates to a density ratio of 1,726 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Colebee's growth rate of 22.3% since the 2021 census exceeded both the state (7.8%) and Greater Sydney, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by interstate migration contributing approximately 75.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, 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. Considering the projected demographic shifts, exceptional growth is predicted over the period with the suburb expected to increase by 4,120 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 68.5% in total over the 17 years.
