Interstate migration accounted for approximately 74.0% of overall population gains during recent periods, with other drivers such as overseas migration and natural growth also being positive factors.

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, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using a method of weighted aggregation of population growth from LGA to SA2 levels. Future projections show an above median population growth for regional areas nationally, with Light expected to expand by 1,931 persons to 2041, reflecting an 18.0% increase over the 16-year period based on the latest annual ERP population numbers.

AreaSearch assessment of residential approval activity sees Light among the top 30% of areas assessed nationwide

Light has averaged approximately 61 new dwelling approvals per year over the past five financial years, totalling 307 homes. As of FY26, 22 approvals have been recorded. Each dwelling has accommodated an average of 2.8 new residents annually between FY21 and FY25, indicating strong demand that supports property values. The average construction cost value for these dwellings is $221,000, aligning with regional trends.

This year, Light has seen $29.0 million in commercial development approvals, reflecting high levels of local commercial activity. Compared to the Rest of SA, Light maintains similar construction rates per person, preserving market balance consistent with the broader area, although recent periods have shown some moderation in development activity. All recent building activity consists of detached houses, maintaining the area's low density nature and attracting space-seeking buyers.

With around 262 people per dwelling approval, Light is demonstrating a developing market. According to AreaSearch's latest quarterly estimate, Light is projected to grow by 1,916 residents by 2041. Construction pace is currently reasonable with projected growth, but buyers may face increasing competition as population increases.
