AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Projections indicate a decline in overall population, with the area's population expected to decline by 93 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to grow by 306 people. See the age section for more details.

The level of residential development activity in Peterborough - Mount Remarkable is very low in comparison to the average area assessed nationally by AreaSearch

Peterborough - Mount Remarkable has seen around 8 new homes approved per year, totalling 43 homes over the past 5 financial years. So far in FY-26, 4 approvals have been recorded. As the area has experienced population decline, development activity has been adequate in relative terms, which is a positive for buyers, while new properties are constructed at an average value of $250,000. Additionally, $4.8 million in commercial development approvals have been recorded this financial year, demonstrating the area's primarily residential nature.

When measured against the Rest of SA, Peterborough - Mount Remarkable records 19.0% less building activity (per person) and places within the 22nd percentile of areas assessed nationally, meaning somewhat limited buyer options and strengthening demand for established dwellings. This is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. Meanwhile, new construction has consisted entirely of detached dwellings, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 812 people in the area per dwelling approval reflects its quiet, low activity development environment.

With the population expected to remain stable or decline, Peterborough - Mount Remarkable should see reduced pressure on housing, potentially creating opportunities for buyers.
