For projections, AreaSearch adopts ABS/Geoscience Australia's 2024 release with 2022 as the base year for SA2 areas. Beyond this data and post-2032, SA State Government's Regional/LGA projections by age category from 2023 are used, adjusted employing a method of weighted aggregation of population growth from LGA to SA2 levels. By 2041, Christies Beach is projected to grow by 868 persons, reflecting an increase of 13.8% over the 17-year period.
