AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections are used, based on 2021 data and adjusted employing a method of weighted aggregation of population growth from LGA to SA2 levels. According to these projections, the suburb is expected to grow by an above median rate, with an increase of 811 persons projected by 2041, reflecting a gain of 10.8% in total over the 17 years.
