The labour market performance in Waterloo lags significantly behind most other regions nationally

Waterloo has a highly educated workforce with significant representation in the technology sector. Its unemployment rate is 8.4%, according to AreaSearch's aggregation of statistical area data.

As of September 2025, Waterloo has 10,552 residents employed, an unemployment rate that is 4.2% higher than Greater Sydney's rate of 4.2%. Workforce participation in Waterloo is at 64.2%, slightly above Greater Sydney's 60.0%. The leading employment industries among Waterloo residents are professional & technical services, finance & insurance, and health care & social assistance. Waterloo shows strong specialization in professional & technical services, with an employment share of 1.7 times the regional level.

However, health care & social assistance is under-represented, with only 9.6% of Waterloo's workforce compared to 14.1% in Greater Sydney. The predominantly residential area appears to offer limited local employment opportunities, as indicated by the difference between the Census working population and resident population counts. From September 2024 to September 2025, Waterloo experienced a 1.3% decrease in labour force alongside a 1.7% decline in employment, causing its unemployment rate to rise by 0.4 percentage points. In contrast, Greater Sydney saw employment growth of 2.1% and labour force growth of 2.4%, with a slight rise in unemployment rate by 0.2 percentage points. State-level data from NSW shows employment contracted by 0.03% (losing 2,260 jobs) as of 25-Nov, with the state unemployment rate at 3.9%. Nationally, the unemployment rate is 4.3%. Jobs and Skills Australia's national employment forecasts from May-25 suggest that while overall employment is projected to expand by 6.6% over five years and 13.7% over ten years, growth rates vary significantly between industry sectors. Applying these projections to Waterloo's employment mix indicates local employment should increase by 7.2% over five years and 14.3% over ten years, though this is a simplified extrapolation for illustrative purposes and does not account for localized population projections.
