By Nov 2025, the estimated population of Crystal Brook (SA) is around 1,598. This figure reflects a growth of 61 people since the 2021 Census, which reported a population of 1,537. The increase is inferred from AreaSearch's estimation of the resident population at 1,562 in Jun 2024, based on ABS ERP data, and an additional 31 validated new addresses since the Census date.

Over the past decade, Crystal Brook has shown resilient growth with a compound annual growth rate of 0.3%, outpacing its SA3 area. Interstate migration was the primary driver of this growth.

AreaSearch uses 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, SA State Government's Regional/LGA projections are adopted, adjusted using a method of weighted aggregation from LGA to SA2 levels. Considering these projections, Crystal Brook is expected to grow by 47 persons by 2041, reflecting an increase of 1.3% over the 17-year period.

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

Crystal Brook saw an average of 3 approvals per year for property development between 2014 and 2018, totaling 19 approvals over these five years. This low level of development activity reflects the rural nature of the area, where housing needs often drive development rather than broader market demand. It is important to note that with such a small number of approvals, individual projects can significantly impact annual growth and relativity statistics.

Compared to Rest of SA and national patterns, Crystal Brook shows significantly less construction activity. Recent development in the area has consisted entirely of detached dwellings, reflecting its rural character where larger properties are typical. As of 2021, there were an estimated 392 people per dwelling approval in the area, indicating a quiet, low activity development environment. According to AreaSearch's latest quarterly estimate, Crystal Brook is forecasted to gain 21 residents by 2041.

With current construction levels, housing supply should meet demand adequately, creating favorable conditions for buyers and potentially enabling growth that exceeds current forecasts.
