Light

Population growth drivers in Light are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

Light's population was around 10,671 as of November 2025. This reflected an increase of 874 people since the 2021 Census, which reported a population of 9,797 people. The change was inferred from the estimated resident population of 10,534 in June 2024 and an additional 160 validated new addresses since the Census date. This level of population resulted in a density ratio of 9.6 persons per square kilometer. Light's growth of 8.9% since the 2021 census exceeded the SA4 region (7.1%) and the Rest of SA, marking it as a growth leader in the region. Interstate migration contributed approximately 74.6% of overall population gains during recent periods.

AreaSearch adopted 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 were adopted, released in 2023 based on 2021 data, with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Future population trends projected an above median growth for national regional areas, with the area expected to grow by 1,978 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 17.2% in total over the 17 years.

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

Light has recorded approximately 61 residential properties granted approval annually. Over the past five financial years, from FY21 to FY25, around 307 homes have been approved, with an additional 14 approved so far in FY26. On average, about 2.8 people per year moved to the area for each new home constructed during these years, indicating healthy demand which should support property values.

New homes are being built at an average construction cost value of $221,000, aligning with regional trends. This financial year has seen $29.0 million in commercial approvals registered, suggesting robust local business investment. Comparatively, Light shows comparable development activity per person to the Rest of SA, maintaining market balance consistent with the broader area.

However, development activity has moderated in recent periods. Recent building activity consists entirely of standalone homes, preserving the area's traditional low density character and focus on family homes appealing to those seeking space. The location currently has approximately 262 people per dwelling approval, indicating room for growth. Population forecasts indicate that Light will gain around 1,841 residents through to 2041, according to the latest AreaSearch quarterly estimate. Current development appears well-matched to future needs, supporting steady market conditions without extreme price pressure.

Employment performance in Light exceeds national averages across key labour market indicators

Light features a balanced workforce spanning white and blue collar employment. The manufacturing and industrial sectors are strongly represented. The unemployment rate is 2.9%.

There has been an estimated employment growth of 1.5% over the past year. As of September 2025, there are 5,397 residents in work. The unemployment rate is 2.4% below Rest of SA's rate of 5.3%. Workforce participation is at 64.9%, compared to Rest of SA's 58.5%.

According to Census responses, 10.6% of residents work from home. Key industries of employment among residents are manufacturing, health care & social assistance, and agriculture, forestry & fishing. Light has a particular employment specialization in manufacturing, with an employment share of 1.6 times the regional level. However, agriculture, forestry & fishing employs only 11.0% of local workers, below Rest of SA's 14.5%. The area appears to offer limited employment opportunities locally, as indicated by the count of Census working population vs resident population. Over a 12-month period, employment increased by 1.5%, while labour force grew by 2.2%, causing the unemployment rate to rise by 0.7 percentage points. In contrast, Rest of SA saw employment rise by 0.3%, labour force grow by 2.3%, and unemployment rise by 1.9 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 offer further insight into potential future demand within Light. These projections suggest that national employment should expand by 6.6% over five years and 13.7% over ten years. Applying these industry-specific projections to Light's employment mix suggests local employment should increase by 5.1% over five years and 11.7% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections.
