Jobs and Skills Australia's national employment forecasts from May-25 suggest that national employment will expand by 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between industry sectors. Applying these projections to Portarlington's employment mix indicates local employment should increase by 6.8% over five years and 13.9% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
