Christie Downs

Christie Downs is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Christie Downs' estimated population, as of November 2025, is around 5,458. This figure reflects a growth of 219 people since the 2021 Census, which reported a population of 5,239. The increase was inferred from AreaSearch's estimation of the resident population at 5,376 in June 2024, based on the latest ERP data release by the ABS and an additional 41 validated new addresses since the Census date. This results in a density ratio of 1,711 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Christie Downs' growth rate of 4.2% since the census places it within 2.0 percentage points of the SA3 area's growth rate of 6.2%. Overseas migration contributed approximately 56.99999999999999% of overall population gains during recent periods, with all drivers including natural growth and interstate migration being positive factors.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjustments made using weighted aggregation methods from LGA to SA2 levels. Considering projected demographic shifts, Christie Downs (SA2) is expected to increase by just below the median of national statistical areas. By 2041, it is projected to have an additional 526 persons, reflecting a total increase of 7.6% over the 17-year period.

AreaSearch assessment of residential development drivers sees a low level of activity in Christie Downs, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers indicates Christie Downs has received around 18 dwelling approvals per year on average over the past five financial years, totalling an estimated 90 homes. As of FY-26, 25 approvals have been recorded. This results in approximately 1.2 new residents arriving per new home annually between FY-21 and FY-25, indicating a balanced supply and demand market with stable conditions. The average construction cost value for new dwellings is $280,000.

In FY-26, commercial development approvals have reached $45.4 million, suggesting strong commercial development momentum. Compared to Greater Adelaide, Christie Downs shows around 69% of the construction activity per person and ranks in the 32nd percentile nationally, implying relatively constrained buyer choice favouring existing dwellings due to market maturity and potential development constraints. New developments consist of 86.0% standalone homes and 14.0% attached dwellings, maintaining Christie Downs' suburban character focused on family homes. The area has around 534 people per approval, reflecting a mature market.

According to AreaSearch's latest quarterly estimate, Christie Downs is projected to grow by 416 residents by 2041. Given current development patterns, new housing supply should meet demand, offering favourable conditions for buyers and potentially facilitating population growth beyond projections.

Christie Downs has emerging levels of nearby infrastructure activity, ranking in the 24thth percentile nationally

AreaSearch assessment indicates Christie Downs faces employment challenges relative to the majority of Australian markets

Christie Downs has a balanced workforce with both white and blue collar jobs. Essential services sectors are well represented, with an unemployment rate of 15.4% as of September 2025.

There was estimated employment growth of 4.6% in the past year based on AreaSearch data aggregation.

Workforce participation lagged significantly at 42.9%, compared to Greater Adelaide's 61.7%. Leading employment industries among residents included health care & social assistance, retail trade, and construction.

Retail trade showed particularly strong specialization with an employment share 1.6 times the regional level. Professional & technical services had lower representation at 3.2% versus the regional average of 7.3%. The area appears to offer limited local employment opportunities as indicated by Census data on working population compared to resident population. In the previous 12 months, employment increased by 4.6% while labour force increased by 2.6%, causing a 1.6 percentage point drop in unemployment rate. Greater Adelaide experienced employment growth of 3.0% and labour force growth of 2.9%, with a 0.1 percentage point drop in unemployment rate. State-level data to 25-Nov-25 showed SA employment grew by 1.19% year-on-year, adding 10,710 jobs, with the state unemployment rate at 4.0%. This compared favourably to the national unemployment rate of 4.3%, with SA's employment growth outpacing the national average of 0.14%. Jobs and Skills Australia's national employment forecasts from May-25 suggested potential future demand within Christie Downs, projecting national employment expansion by 6.6% over five years and 13.7% over ten years. Applying these projections to Christie Downs' employment mix indicated local employment should increase by approximately 6.2% over five years and 13.2% over ten years, though this is a simple extrapolation for illustrative purposes and does not account for localized population projections.
