For areas not covered by this data, AreaSearch utilises the VIC State Government's Regional/LGA projections released in 2023, adjusting with a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Considering these projected demographic shifts, the suburb is expected to grow by 1,596 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 16.9% in total over the 17-year period.
