According to Census responses, 61.6% of residents worked from home, potentially influenced by Covid-19 lockdowns.

The area appeared to offer limited local employment opportunities, as indicated by the count of Census working population versus resident population. Between December 2024 and December 2025, employment levels increased by 0.4%, while labour force grew by 1.0%, leading to a rise in unemployment rate by 0.5 percentage points. In comparison, Greater Sydney recorded employment growth of 2.2% and labour force growth of 2.3%, with only marginal changes in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 suggested potential future demand within Petersham. These projections estimated national employment to expand by 6.6% over five years and 13.7% over ten years, with significant variations between industry sectors. Applying these industry-specific projections to Petersham's employment mix indicated local employment should increase by 7.2% over five years and 14.5% over ten years, though this was a simple weighting extrapolation for illustrative purposes and did not account for localized population projections.
