Bonnie Brook

Bonnie Brook lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Bonnie Brook's population is estimated at around 4,596 as of Feb 2026. This reflects an increase of 4,263 people (1280.2%) since the 2021 Census, which reported a population of 333 people. The change is inferred from the resident population of 4,568, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 2,730 validated new addresses since the Census date. This level of population equates to a density ratio of 215 persons per square kilometer, providing significant space per person and potential room for further development. Bonnie Brook's 1280.2% growth since the 2021 census exceeded the national average (9.9%), along with the state, marking it as a growth leader in the region. Population growth for the area was primarily driven by interstate migration that contributed approximately 88.0% 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, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the VIC State Government's Regional/LGA projections released in 2023 with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are also applied across all areas for years 2032 to 2041. Considering the projected demographic shifts, exceptional growth, placing in the top 10 percent of national areas, is predicted over the period with the suburb of Bonnie Brook expected to increase by 4,393 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 10.9% in total over the 17 years.
