AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For areas not covered and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and released in 2023. Future population trends indicate an expected increase just below the median for statistical areas analysed by AreaSearch, with the suburb expected to grow by 157 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 4.8% over the 16 years.

Conversely, professional & technical services showed lower representation at 3.7%, compared to the regional average of 7.3%. The area may offer limited local employment opportunities, as indicated by the count of Census working population versus resident population. Over a 12-month period ending in May-25, employment increased by 4.0% alongside labour force growth of 2.9%, resulting in a 1.0 percentage point drop in unemployment. In contrast, Greater Adelaide experienced employment growth of 4.2% and labour force growth of 3.9%, with a 0.3 percentage point drop in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 project national employment to expand by 6.6% over five years and 13.7% over ten years, with varying growth rates between industry sectors. Applying these projections to Sellicks Beach's employment mix suggests local employment should increase by 6.3% over five years and 13.3% over ten years, based on a simple weighting extrapolation for illustrative purposes.
