This shows an increase of 279 people since the 2021 Census, which reported a population of 4,380.

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 adopted with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. Considering projected demographic shifts, a population increase just below the median is expected for Coromandel Valley, with an estimated expansion of 458 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 9.8% over the 16 years.

Residential development activity is lower than average in Coromandel Valley according to AreaSearch's national comparison of local real estate markets

Coromandel Valley has seen approximately four new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Between FY-21 and FY-25, around 23 homes were approved, with two more approved in FY-26. On average, nine people moved to the area for each dwelling built over these five financial years.

This demand outpaces supply, potentially putting upward pressure on prices and increasing competition among buyers. New dwellings are developed at an average expected construction cost of $276,000. In FY-26, $2.4 million in commercial approvals have been registered, indicating the area's primarily residential nature. Compared to Greater Adelaide, Coromandel Valley records significantly lower building activity, at 79.0% below the regional average per person. This constrained new construction typically reinforces demand and pricing for existing dwellings.

The level is also below national average, suggesting possible planning constraints. All new constructions since FY-21 have been standalone homes, maintaining the area's traditional suburban character with a focus on family homes. With around 1536 people per dwelling approval, Coromandel Valley reflects a highly mature market. According to AreaSearch's latest quarterly estimate, the population is forecasted to grow by 458 residents through to 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
