A Napthine Government plan to create 200,000 jobs over five years – touted as the most comprehensive employment blueprint in Victoria's history – does not appear to have involved formal advice from state Treasury.

Instead, the prediction of an employment surge was made by Premier Denis Napthine's own department, which typically does not provide economic forecasts or modelling.

Since December 2010, state jobs growth has failed to keep pace with booming population growth, pushing Victoria's unemployment rate to 6.8 per cent, the highest since 2001.

Over the past four years, employment has increased by an annual average of 22,000. This is well below the annual average jobs growth of 40,000 needed to achieve the forecast over the next five years.
