AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using weighted aggregation from LGA to SA2 levels. By 2041, population projections indicate a decline of 41 persons overall, but growth is anticipated in specific age cohorts, notably the 75 to 84 age group with an expected increase of 118 people.

AreaSearch assessment of residential development drivers sees a low level of activity in Quorn - Lake Gilles, placing the area among the bottom 25% of areas assessed nationally

Quorn - Lake Gilles has recorded approximately nine residential properties granted approval each year. Development approval data is produced by the Australian Bureau of Statistics on a financial year basis, totalling 47 approvals across the past five financial years from FY20 to FY25, with zero approvals so far in FY26. Over these five years, an average of 0.1 new residents per year per dwelling constructed has been recorded. This indicates that new supply is keeping pace with or exceeding demand, providing ample buyer choice and creating capacity for population growth beyond current forecasts.

The average construction value of new homes over this period is $430,000. Additionally, $1.2 million in commercial approvals have been registered during the current financial year, reflecting the area's residential nature. Compared to the Rest of SA, Quorn - Lake Gilles records 168.0% more construction activity per person, offering buyers ample choice, although development activity has moderated in recent periods. This is lower than the national average, suggesting market maturity and possible development constraints. New building activity comprises 50.0% detached houses and 50.0% medium and high-density housing, marking a significant shift from existing housing patterns which are currently 94.0% houses. This change may be due to diminishing developable land availability and evolving lifestyle preferences and housing affordability needs. The estimated population count of 402 people per dwelling approval reflects the area's quiet, low activity development environment.

With stable or declining population projections, Quorn - Lake Gilles should experience reduced housing demand pressures, benefiting potential buyers.
