An expanded public sector workforce and wage growth has cost Victoria more than $1.6 billion in the past financial year, a new annual report shows.
The Auditor-General's annual report released on Wednesday showed that in June there were 238,928 public servants, compared to 213,557 in June 2013.
Costs jumped because of "additional employee expenses" mainly due to wage growth and additional staff, the report read.
"The public sector workforce has grown faster than the Victorian population."
Main areas of jobs growth were education, health, transport and justice.
The public services union has supported the jobs news after years of cuts from the previous government.
"Victoria's population has grown 20 per cent in the last 10 years and the number of staff delivering many public services is less than 20 years ago," Community and Public Sector Union secretary Karen Batt said.
The former government wasted $300 million on redundancies and cutting 6000 jobs in the public sector and then spent millions on labour hire to do the work, Ms Batt added.
