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 or years post-2032, the SA State Government's Regional/LGA projections are adopted and adjusted using a weighted aggregation method from LGA to SA2 levels. Future population projections indicate significant growth for North Plympton, with an expected increase of 1,118 persons by 2041, reflecting a total increase of 21.5% over the 17-year period.

Recent residential development output has been above average within North Plympton when compared nationally

North Plympton saw approximately 34 new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Around 170 homes were approved between FY21-FY25, with 15 more approved in FY26 so far. Each year, an average of 1.4 new residents per dwelling was estimated over the past five financial years.

This indicates a balanced supply and demand market supporting stable conditions. The average construction cost value for new homes was $379,000, suggesting developers target the premium market segment with higher-end properties. In FY26, $18.9 million in commercial approvals have been registered, indicating balanced commercial development activity. Comparatively, North Plympton has seen 41.0% more development per person than Greater Adelaide over the past five years, maintaining good buyer choice while supporting existing property values. However, recent periods show a moderation in development activity.

The new building activity is composed of 42.0% standalone homes and 58.0% medium to high-density housing, offering affordable entry pathways for downsizers, investors, and first-time purchasers. This shift from the area's existing housing (70.0% houses) reflects decreasing developable sites and changing lifestyles. With approximately 146 people per dwelling approval, North Plympton's market is expanding. Population forecasts indicate an increase of 875 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
